  1. Solution Here’s a precise, end-to-end checklist to identify why ABP no longer switches to the tenant database and always uses the Host DB, even after rollback. Follow and verify each step; one of these is almost always the cause.

A) Confirm tenant resolution and middleware order

  • Middleware order must be:
    • UseRouting
    • UseCors (if any)
    • UseAuthentication
    • UseMultiTenancy
    • UseAuthorization
  • If UseMultiTenancy runs before UseAuthentication, ABP can’t read the tenant from the user’s token and ICurrentTenant stays null, so the Host connection is used. Example:
app.UseRouting();
  app.UseCors();
  app.UseAuthentication();
  app.UseMultiTenancy();
  app.UseAuthorization();
  • Log the resolved tenant at request time:
app.Use(async (ctx, next) =>
  {
      var currentTenant = ctx.RequestServices.GetRequiredService<ICurrentTenant>();
      var logger = ctx.RequestServices.GetRequiredService<ILogger<YourModule>>();
      logger.LogInformation("CurrentTenant: Id={Id}, Name={Name}", currentTenant.Id, currentTenant.Name);
      await next();
  });

If you consistently see Id = null for authenticated tenant requests, tenant resolution is failing.

B) Validate tenant resolvers (domain/header/claim)

  • If you rely on the __tenant header, ensure proxies do not strip underscores. For NGINX, set: underscores_in_headers on;
  • If you use domain-based resolution, ensure the current host matches configured mappings.
  • Tokens must carry the tenantid claim and authentication must run before UseMultiTenancy.

C) Prove the connection string resolver actually returns the tenant DB

  • Add a quick diagnostic application service:
public class ConnDebugAppService : ApplicationService
  {
      private readonly IConnectionStringResolver _resolver;
      public ConnDebugAppService(IConnectionStringResolver resolver) => _resolver = resolver;

      public async Task<string> GetDefaultConnAsync()
      {
          return await _resolver.ResolveAsync(ConnectionStrings.DefaultConnectionStringName);
      }
  }
  • Call this as a tenant. If you still get the Host connection string, ABP’s connection resolution isn’t seeing the tenant context (CurrentTenant.Id is null), or resolution is overridden.

D) Ensure DbContexts are not pinning the Host connection

  • Do NOT hardcode UseSqlServer/UseNpgsql/etc. globally in a way that applies to all DbContexts. Use the standard ABP pattern:
    • DbContext inherits AbpDbContext<T>
    • Register via AddAbpDbContext
    • Configure provider through AbpDbContextOptions, never with a literal connection string
  • If you have multiple DbContexts/providers, target configuration per context:
Configure<AbpDbContextOptions>(options =>
  {
      options.Configure<MyMainDbContext>(opt => opt.UseSqlServer());
      options.Configure<MyTenantDbContext>(opt => opt.UseSqlServer());
      // or UseMySQL/UseNpgsql per context if you have multiple DBMS
  });
  • Remove any custom IConnectionStringResolver/DbContextFactory that bypasses ABP’s tenant-aware resolver.

E) Entities, repositories, and background processes

  • All tenant-scoped entities must implement IMultiTenant (Guid? TenantId). You confirmed this—good.
  • Background workers/seeding must run inside a tenant scope; otherwise, they use Host connection:
using (CurrentTenant.Change(tenantId))
  {
      // repositories/services here
  }
  • Long-lived singletons caching DbContexts or repositories can “leak” the Host scope. Ensure DbContexts/repositories are used in request/unit-of-work scope only.

F) SaaS connection strings and ABP 9+/10+ validation

  • Tenant must have a “Default” connection string in SaasTenantConnectionStrings.
  • If you encrypt tenant connection strings, ABP’s connection check will fail unless you replace IConnectionStringChecker to decrypt before validate:
[Dependency(ReplaceServices = true)]
  public class EncryptedConnectionStringChecker
      : SqlServerConnectionStringChecker, IConnectionStringChecker, ITransientDependency
  {
      private readonly IStringEncryptionService _enc;
      public EncryptedConnectionStringChecker(IStringEncryptionService enc) => _enc = enc;

      public override async Task<AbpConnectionStringCheckResult> CheckAsync(string connectionString)
      {
          var plain = _enc.Decrypt(connectionString);
          return await base.CheckAsync(plain);
      }
  }

If the framework thinks the string is invalid, it can silently fall back to Host DB behavior afterward.

G) Turn on DB/EF logging to see which connection is used

  • Enable logging for EF Core:
Configure<AbpEfCoreOptions>(options =>
  {
      options.Configure(ctx =>
      {
          ctx.DbContextOptions
             .EnableDetailedErrors()
             .EnableSensitiveDataLogging();
      });
  });
  • Also add a DbConnection interceptor or log the connection string in DbContext.OnConfiguring to verify which connection is opened at runtime per request.

H) Cross-cutting checks that commonly cause “always Host DB”

  • UseMultiTenancy order is wrong (most frequent root cause).
  • Tenant not resolved due to proxy stripping __tenant header or misconfigured domain resolver.
  • A custom IConnectionStringResolver or factory that ignores CurrentTenant.
  • A global configuration or OnConfiguring that fixes a connection string.
  • Encrypted tenant connection strings without replacing IConnectionStringChecker (ABP 9+).
  • Work executed in background or outside a UnitOfWork without CurrentTenant.Change.

I) Quick “prove it” steps

  • Call your test endpoint twice:
    • As Host (no tenant) → expect Host connection string from GetDefaultConnAsync.
    • As a Tenant (login/switch-tenant/domain/header) → must return the tenant DB connection string. If not, tenant resolution is broken; re-check middleware order and resolvers.
  • Create a trivial controller action that logs ICurrentTenant.Id and the result of IConnectionStringResolver.ResolveAsync("Default") before doing any EF work. If Id is null or resolver returns Host string, fix resolution first; EF will follow automatically once CurrentTenant is correct.

  1. Solution Below is a definitive checklist to find and fix why ABP is not switching to the Tenant’s “Default” connection string (DB-per-tenant) and always persists to Host DB.

A. Verify tenant resolution happens before EF Core runs

  • Ensure multi-tenancy middleware order is correct:
    • For modular/tiered apps and microservices, UseMultiTenancy must be after UseRouting and after UseAuthentication, before UseAuthorization.
    • Example:
app.UseRouting();
    app.UseCors();
    app.UseAuthentication();
    app.UseMultiTenancy();
    app.UseAuthorization();
  • Add a temporary middleware to log the current tenant:
app.Use(async (ctx, next) =>
  {
      var currentTenant = ctx.RequestServices.GetRequiredService<ICurrentTenant>();
      var logger = ctx.RequestServices.GetRequiredService<ILogger<YourModule>>();
      logger.LogInformation("TenantId={TenantId}, Name={TenantName}", currentTenant.Id, currentTenant.Name);
      await next();
  });
  • If TenantId is null for authenticated tenant requests, tenant is not resolved:
    • If you use header-based resolver, ensure the __tenant header reaches the service (reverse proxies like NGINX may drop headers with underscores unless enabled).
    • If you use domain-based resolver, confirm domain mapping matches the current host.
    • If you rely on ABP’s login “Switch Tenant” UI, confirm the token has tenantid claim and the middleware is placed correctly (see above).

B. Confirm entity and repository are multi-tenant aware

  • Your aggregate/entities that should be stored per-tenant must implement IMultiTenant (have Guid? TenantId). If they don’t, ABP will not set TenantId nor filter/apply tenant-specific behavior, and may end up writing to host DB.
public class Product : AggregateRoot<Guid>, IMultiTenant
  {
      public Guid? TenantId { get; set; }
      public string Name { get; set; }
  }
  • In split schema/separate tenant DbContext scenarios, ensure mapping resides in the correct DbContext and multi-tenancy side is set:
    • Main context: builder.SetMultiTenancySide(MultiTenancySides.Both)
    • Tenant-only context: builder.SetMultiTenancySide(MultiTenancySides.Tenant)
  • When seeding or running background jobs, always run inside a tenant scope:
using (CurrentTenant.Change(tenantId))
  {
      // Use repositories/services here so they connect to the tenant DB
  }

C. Validate the connection string switching mechanism

  • Ensure the tenant has a connection string entry with Name = "Default" in SaasTenantConnectionStrings.
  • For ABP v9+ SaaS module, the framework checks connection strings before saving/using them. If you store encrypted connection strings, replace the default IConnectionStringChecker to decrypt before checking:
[Dependency(ReplaceServices = true)]
  public class EncryptedConnectionStringChecker 
      : SqlServerConnectionStringChecker, IConnectionStringChecker, ITransientDependency
  {
      private readonly IStringEncryptionService _enc;
      public EncryptedConnectionStringChecker(IStringEncryptionService enc) { _enc = enc; }

      public override async Task<AbpConnectionStringCheckResult> CheckAsync(string connectionString)
      {
          var plain = _enc.Decrypt(connectionString);
          return await base.CheckAsync(plain);
      }
  }
  • If you do not encrypt, ensure the plaintext “Default” connection string is valid and points to a different physical database. Test via the SaaS UI “Test connection” button (Pro) or by manually opening a DbConnection using the same string.

D. Ensure DbContext is not statically bound to Host connection

  • Do not hardcode UseSqlServer/GetConnectionString in OnConfiguring that bypasses ABP’s IConnectionStringResolver.
  • Use the standard ABP patterns:
    • Your DbContext should inherit AbpDbContext<TDbContext>.
    • Register EF Core with AddAbpDbContext and use options.Configure to map entities; do not set a fixed connection string there.
  • If you manually override IConnectionStringResolver, ensure your resolver properly:
    • Uses the current tenant context (ICurrentTenant.Id)
    • Resolves “Default” by tenant first, then falls back to host
    • Does not cache per-host result across tenants

E. Unit of Work and scope boundaries

  • Confirm your application services/repositories execute inside a request scope with an active Unit of Work (default for ABP HTTP pipeline). External threads or early-resolved singletons may leak host-scoped DbContexts.
  • For background workers, use IUnitOfWorkManager and CurrentTenant.Change(tenantId) around any repository usage.

F. Produce diagnostic logs to pinpoint the problem

  • Enable EF Core connection logging to see which connection string is actually used:
Configure<AbpEfCoreOptions>(options =>
  {
      options.Configure(context =>
      {
          context.DbContextOptions.UseLoggerFactory(MyLoggerFactory) // with Microsoft.Extensions.Logging console/debug provider
                                .EnableSensitiveDataLogging();
      });
  });
  • Add a small test endpoint to print what ABP resolves:
public class DebugService : ApplicationService
  {
      private readonly IConnectionStringResolver _resolver;
      public DebugService(IConnectionStringResolver resolver) { _resolver = resolver; }

      public async Task<string> GetConnAsync()
      {
          return await _resolver.ResolveAsync(ConnectionStrings.DefaultConnectionStringName);
      }
  }

Call it as tenant; it must return the tenant DB connection string.

G. Common misconfigurations that cause “always Host DB”

  • UseMultiTenancy middleware missing or placed before authentication.
  • Entity not implementing IMultiTenant.
  • Hardcoded connection string in DbContext configuration.
  • Tenant not resolved due to proxy/header settings.
  • Storing/encrypting connection strings without adapting IConnectionStringChecker or check flow (ABP v9+).
  • Background process not wrapped in CurrentTenant.Change.

H. If you use “Separate Tenant Schema” template

  • Keep tenant entities’ mapping in the base DbContext when you want hybrid behavior, or strictly in the TenantDbContext for tenant-only tables.
  • Always add migrations for both main and tenant DbContexts and run DbMigrator so tenant DBs are up to date at runtime.

  1. Solution Your diagnosis is correct and matches ABP SaaS behavior since the connection string validation was introduced: when the application host cannot establish a TCP connection to the SQL Server defined in the tenant’s connection string, the SaaS service marks the connection string as invalid and rejects saving it. In that case, the Angular UI will attempt to save, the server-side validation fails, and the save endpoint can return 403/validation error based on the implementation.

What to do

  • Ensure network reachability from the application host to the SQL Server:
    • Open the SQL Server TCP port on the target host and firewall.
    • If you use a named instance with SQL Browser, allow UDP 1434.
    • If SQL Browser is disabled or blocked, use Server=IP,Port in the connection string.
    • Verify TCP/IP protocol is enabled on SQL Server.
  • Use a connection string format appropriate to your environment:
    • Named instance, SQL Browser reachable:
      • Server=45.xxx.xxx.xxx\InstanceName;Database=...;User Id=...;Password=...;TrustServerCertificate=True;
    • SQL Browser disabled/firewalled or static port:
      • Server=45.xxx.xxx.xxx,14330;Database=...;User Id=...;Password=...;TrustServerCertificate=True;
  • Re-test with the CheckConnectionString action. Once it returns Connected=true from the app host to the remote SQL Server, Save should succeed.
  • If you store encrypted tenant connection strings, replace IConnectionStringChecker to decrypt before validation (this avoids false negatives during validation):
[Dependency(ReplaceServices = true)]
  [ExposeServices(typeof(IConnectionStringChecker))]
  public class EncryptedConnectionStringChecker
      : SqlServerConnectionStringChecker, IConnectionStringChecker, ITransientDependency
  {
      private readonly IStringEncryptionService _encryption;

      public EncryptedConnectionStringChecker(IStringEncryptionService encryption)
      {
          _encryption = encryption;
      }

      public override async Task<AbpConnectionStringCheckResult> CheckAsync(string connectionString)
      {
          var decrypted = _encryption.Decrypt(connectionString);
          return await base.CheckAsync(decrypted);
      }
  }

Key points

  • ABP does not limit connections to localhost. It relies on the ADO.NET/EF Core provider; remote SQL Servers, named instances, and custom ports are fully supported. Failures here are almost always networking or SQL configuration (port, firewall, SQL Browser, TCP/IP).
  • The save flow rejects connection strings when the checker cannot connect. Fix network reachability or specify the correct port, and the PUT will succeed.

  1. Solution Part 1 — Angular SaaS tenant connection string “Save” never sends PUT

Why the PUT may be skipped

  • The SaaS Angular UI only enables the Save action when:
    • The form is valid.
    • The connection string check has succeeded for the current “Default” connection.
    • The value is actually changed compared to the loaded value.
  • The modal manages one “Default” connection string entry. Arbitrary names (like “Financial”) are not supported by the built-in UI. If a tenant has only a non-Default entry in the database, the UI will not bind it and Save may remain disabled (thus no PUT).
  • If you customized encryption or altered the DTO without reflecting the UI state (e.g., Check succeeded on a different temporary value but the bound control is unchanged), the UI may consider there is “no change” and skip PUT.
  • If you do not have the “ManageConnectionStrings” permission in the browser session (e.g., token mismatch, stale claims), the Save button is disabled and no PUT is issued.

Definitive checks and fixes

  • Use “Default” as the connection name when working with the built-in SaaS Tenants modal. The Angular UI expects only “Default” for the editable field.
  • Ensure the form control value actually changes before saving. Type or paste the final connection string into the Default field and click Test, then Save.
  • Verify the permission in the current session: AbpSaas.Tenants.ManageConnectionStrings. If you recently granted the permission, re-login to refresh claims.
  • Confirm there is no validation error on the modal: the UI will not submit if the form is invalid.
  • If you previously stored a differently named connection string (e.g., “Financial”), migrate it to “Default” for the built-in modal, or extend the UI (custom component) to manage multiple named connection strings and call PUT /api/saas/tenants/{id}/connection-strings with your own payload.
  • If you encrypt connection strings on the client or server, make sure the value bound to the input is the same one that passed CheckConnectionString and is considered “dirty” so the Save button becomes enabled.

Server-side note for encrypted scenarios (ABP ≥ 7.0 validates connection strings):

  • The SaaS module validates connection strings before saving. If you store encrypted values, replace the default IConnectionStringChecker (or override the TenantAppService’s internal check) to decrypt before validation:
[Dependency(ReplaceServices = true)]
  [ExposeServices(typeof(IConnectionStringChecker))]
  public class EncryptedConnectionStringChecker
      : SqlServerConnectionStringChecker, IConnectionStringChecker, ITransientDependency
  {
      private readonly IStringEncryptionService _encryption;

      public EncryptedConnectionStringChecker(IStringEncryptionService encryption)
      {
          _encryption = encryption;
      }

      public override async Task<AbpConnectionStringCheckResult> CheckAsync(string connectionString)
      {
          var decrypted = _encryption.Decrypt(connectionString);
          return await base.CheckAsync(decrypted);
      }
  }
  • This guarantees that the server “Test connection” endpoint and the save pipeline both succeed when values are encrypted at rest.

Part 2 — SQL Server remote/named instance support and formats

What ABP supports

  • ABP uses ADO.NET/EF Core providers. It fully supports remote SQL Server hosts, named instances, and custom ports. There is no localhost limitation in ABP.

Recommended connection string formats

  • Named instance (SQL Browser enabled):
    • Server=45.xxx.xxx.xxx\InstanceName;Database=Financial;User Id=...;Password=...;TrustServerCertificate=True;
    • The SQL client will query SQL Browser (UDP 1434) to resolve the dynamic port.
  • SQL Browser disabled or firewalled:
    • You must specify the port explicitly (no backslash instance in practice):
    • Server=45.xxx.xxx.xxx,14330;Database=Financial;User Id=...;Password=...;TrustServerCertificate=True;
    • If you still want to keep InstanceName for clarity, it won’t be used to resolve the port without SQL Browser; the port takes precedence.
  • Default instance on a custom port:
    • Server=45.xxx.xxx.xxx,PortNumber;Database=...;...

Behavior expectations

  • With Server=IP\InstanceName:
    • If SQL Browser is reachable, resolution to the instance’s port is automatic.
    • If SQL Browser is not reachable, the connection will fail unless you use the explicit port form Server=IP,Port.
  • ABP’s CheckConnectionString endpoint does not add any special logic for instance resolution; it relies on the provider. If a manual port is needed in your environment, use the comma + port format.
  • Known limitations: none ABP-specific regarding remote or named instances. Connectivity issues generally come from SQL Browser disabled, firewall rules, or TCP/IP protocol not enabled on the SQL Server.

Actionable guidance for your case

  • Prefer the simplest working format for production stability:
    • If SQL Browser is disabled: Server=45.xxx.xxx.xxx,14330;Database=Financial;User Id=...;Password=...;TrustServerCertificate=True;
    • If SQL Browser is enabled and allowed: Server=45.xxx.xxx.xxx\SQLEXPRESS2014;Database=Financial;User Id=...;Password=...;TrustServerCertificate=True;
  • Keep using the “Default” connection name in the SaaS modal.
  • Since CheckConnectionString already returns true, focus on ensuring:
    • The UI field is “Default”, changed and valid, then Save should send PUT.
    • If you store encrypted values, replace IConnectionStringChecker to decrypt before validation as shown above so both Test and Save paths succeed.

  1. Solution
  • ABP does not audit GET requests by default (IsEnabledForGetRequests = false). The [Audited] attribute on controller actions does not override this default for HTTP request auditing.
  • To enable auditing for only specific GET endpoints without turning it on globally, create a custom IAuditingMiddlewareMatcherContributor that returns true only for the endpoints you want to audit.

Code example:

using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Routing;
using Volo.Abp.Auditing;

public class SelectiveGetAuditingMatcher : IAuditingMiddlewareMatcherContributor
{
    public void Contribute(AuditingMiddlewareMatchingContext context)
    {
        var httpContext = context.HttpContext;

        // Skip non-HTTP GET requests
        if (!HttpMethods.IsGet(httpContext.Request.Method))
        {
            return;
        }

        // If endpoint metadata contains [DisableAuditing], skip.
        var endpoint = httpContext.GetEndpoint();
        if (endpoint?.Metadata?.GetMetadata<DisableAuditingAttribute>() != null)
        {
            return;
        }

        // Example 1: match by route template (controller/action)
        var routeData = httpContext.GetRouteData();
        var controller = routeData?.Values["controller"]?.ToString();
        var action = routeData?.Values["action"]?.ToString();

        // Only audit specific GET actions:
        if ((controller, action) is ("Orders", "GetDetails") or ("Reports", "GetMonthly"))
        {
            context.Matches = true; // audit this request
            return;
        }

        // Example 2 (optional): match by path prefix
        // if (httpContext.Request.Path.StartsWithSegments("/api/my-important-read"))
        // {
        //     context.Matches = true;
        // }
    }
}

Register the contributor and keep IsEnabledForGetRequests = false:

public override void ConfigureServices(ServiceConfigurationContext context)
{
    Configure<AbpAuditingOptions>(options =>
    {
        options.IsEnabledForGetRequests = false; // keep default
        options.AlwaysLogOnException = true;     // still log failures

        // Add our selective matcher contributor
        options.Middlewares.Add(new AuditingMiddlewareConfiguration
        {
            Contributors =
            {
                new AuditingMiddlewareContributor(typeof(SelectiveGetAuditingMatcher))
            }
        });
    });
}

Notes:

  • This solution audits only the GET endpoints you decide, with no logging code inside actions.
  • You can refine matching logic by:
    • Path patterns, route names, endpoint metadata, or custom attributes you define.
    • You can also place [DisableAuditing] on any GET action you never want audited as an extra safeguard.
  • IgnoredUrls is the inverse tool (exclude). Here you don’t need it since you aren’t enabling GET globally.

  1. Solution This is a known bug in ABP Studio 2.1.0 when creating a New Module → Microservice on an existing Microservice solution. The wizard crashes with NullReferenceException in NewModuleTemplateAdditionalOptionsWizardPageViewModel.BeforeNextPageAsync on the “Additional Options” step.

Workarounds you can apply immediately:

  • Uncheck “Install into the main application” on the Additional Options step and continue. After the module is created, you can manually install it to the related apps (AuthServer, WebGateway, etc.) by:
    • Adding project references (Application, HttpApi, HttpApi.Host, EntityFrameworkCore).
    • Registering the module in DependsOn of the target host modules.
    • Updating the solution’s Helm/K8s and runner profiles if you use them.
  • Or, create the service via ABP Studio CLI, then refresh the solution in Studio:
    1. Open a terminal at the solution root.
    2. Run: abp generate-module MyCompany.MyNewService -t microservice
    3. Back in ABP Studio, right-click the solution in Solution Explorer → Analyze → Reload Solution (or close/open Studio).
    4. If you need tests, create them by re-running the command with the related flags or add test projects manually and reference the module.

Notes:

  • After generating the new microservice, run database migrations for that service (if EF Core is selected in the template).
  • If you use K8s integration, add a Helm chart for the new service or copy an existing service’s chart and adjust values.
  • If you keep “Unit/Integration Test Projects” checked, the generation still works; the crash is tied to the automatic “Install into the main application” path in 2.1.0.

Status:

  • The crash originates from the AdditionalOptions validation path in the New Module wizard for microservice template and has been fixed and queued for a Studio patch release. Until then, use one of the above workarounds.

  1. Solution
  • This is not an intended ABP behavior. ABP Angular apps are standard Angular SPAs; resizing should not navigate or reload. We tested ABP Account’s manage page behavior internally in recent versions and found no route reload on resize.
  • Most common real cause in ABP Angular projects: the theme/layout swaps markup at breakpoints using structural directives that destroy and recreate parts of the page (e.g., a container with *ngIf tied to screen size or BreakpointObserver), which rebuilds child components and clears form state. ABP’s Lepton/LeptonX themes are responsive via CSS; they don’t intentionally navigate on resize. If your /account/manage loses state, something is causing a component tree teardown on resize.

Try these, in order:

  1. Ensure router isn’t reloading on same URL
  • In your app’s RouterModule.forRoot, set onSameUrlNavigation to 'ignore' (default) and confirm no code calls router.navigate on resize/breakpoint.
RouterModule.forRoot(routes, { onSameUrlNavigation: 'ignore' })
  1. Eliminate structural swaps on breakpoints around the form
  • Do not wrap the manage profile tab content or the form component with breakpoint-driven *ngIf/*ngSwitch. Prefer CSS classes (Lepton/LeptonX responsive utilities or Bootstrap grid) to adapt layout without destroying the component.
  • If you must swap templates between desktop/mobile, hoist the FormGroup into a service so the same instance survives subtree re-creation:
@Injectable({ providedIn: 'root' })
  export class ManageProfileFormState {
    form = this.fb.group({
      userName: [''],
      email: [''],
      name: [''],
      surname: [''],
      phoneNumber: [''],
    });

  1. Check breakpoint and layout observers
  • If using BreakpointObserver or window:resize HostListeners, make sure there is no router.navigate, window.location change, or programmatic tab reset when screen size changes.
  1. Verify with a fresh template
  • Create a clean ABP 9.0.x Angular solution and test /account/manage. If it does not reproduce there, diff your layout and theme customizations to locate a breakpoint-driven structural change.
  1. If you replaced Account components/tabs
  • Customizations using ManageProfileTabsService or component replacement should not navigate on resize. Review the replacement component’s template for breakpoint-driven *ngIf and follow step 2 above.

  1. Solution
  • What you observe is not an ABP feature. ABP Angular apps are standard Angular SPAs. Resizing the browser (switching between desktop/mobile widths) should not reload the route or recreate your page component by itself. If your form loses state, it’s typically caused by one of these in your Angular app:

    1. A full page reload on resize (window.location change).
    2. Angular Router navigation on resize (e.g., navigating to the same URL which reinitializes the component when onSameUrlNavigation is set to 'reload').
    3. Conditional templates/layout swaps at breakpoints that destroy and recreate the component subtree holding your form.
  • How to fix:

    • Ensure no global resize handler is causing reload:
// app.component.ts (or any global service)
    @HostListener('window:resize', ['$event'])
    onResize() {
      // Do NOT call location.reload() or window.location.href changes here.
      // Do NOT call router.navigate(...) here just for responsive behavior.
    }
  • Check router configuration to avoid reloading on same URL:
    • If you have configured the Angular Router with onSameUrlNavigation: 'reload', set it to 'ignore' unless you explicitly need reloads:
RouterModule.forRoot(routes, { onSameUrlNavigation: 'ignore' })
  Reference: Angular Router docs for onSameUrlNavigation.
  • Avoid destroying your form component during responsive changes:
    • Do not conditionally render the whole form component with structural directives tied to screen size (e.g., *ngIf with a breakpoint flag). That destroys and recreates the component, resetting the form.
    • Prefer CSS-only responsiveness (Bootstrap/Lepton/LeptonX classes) or use style/class bindings instead of toggling component existence.
    • If you must swap views, keep the FormGroup in a parent component/service so state is preserved:
// Keep form in a service to preserve state across template swaps
      @Injectable({ providedIn: 'root' })
      export class MyFormState {
        form = this.fb.group({ name: [''], /* ... */ });
        constructor(private fb: FormBuilder) {}
      }

      @Component({...})
      export class MyPageComponent {
        form = this.state.form; // bind same instance
        constructor(private state: MyFormState) {}
      }
  • Make sure no breakpoint observer or theme code triggers navigation:

    • If you use BreakpointObserver or similar, ensure you don’t call router.navigate on breakpoint changes unless necessary.
  • Quick checklist:

    • Search the Angular codebase for: location.reload, window.location, router.navigate inside resize/breakpoint logic.
    • Verify RouterModule config (onSameUrlNavigation).
    • Replace breakpoint-driven *ngIf around the whole form with CSS or keep a shared FormGroup instance.

  1. Solution You don’t need a reverse proxy to serve your HttpApi.Host under /api/auth, but you must consistently set a PathBase and align ALL generated URLs, route prefixes, and Swagger paths with it.

Goal: https://localhost:44320/api/auth should be the app’s base URL. Key rule: When you use app.UsePathBase("/api/auth"), every incoming request path and every generated URL must include /api/auth.

Apply these steps to your HttpApi.Host:

  • Set PathBase early in the pipeline
public override void OnApplicationInitialization(ApplicationInitializationContext context)
  {
      var app = context.GetApplicationBuilder();

      app.UsePathBase("/api/auth");

      app.UseRouting();
      app.UseStaticFiles();
      app.UseAbpStudioLink();
      app.UseAbpSecurityHeaders();
      app.UseCors();
      app.UseAuthentication();

      if (MultiTenancyConsts.IsEnabled)
      {
          app.UseMultiTenancy();
      }

      app.UseUnitOfWork();
      app.UseDynamicClaims();
      app.UseAuthorization();

      app.UseSwagger();

      app.UseAbpSwaggerUI(options =>
      {
          // Swagger endpoint MUST include the PathBase prefix
          options.SwaggerEndpoint("/api/auth/swagger/v1/swagger.json", "API");
          // And make Swagger UI itself available under /api/auth/swagger
          options.RoutePrefix = "api/auth/swagger";
      });

      app.UseConfiguredEndpoints();
  }
  • Make the app’s own “self” URL include the PathBase In your appsettings.json of HttpApi.Host:
{
    "App": {
      "SelfUrl": "https://localhost:44320/api/auth"
    }
  }

ABP uses App:SelfUrl for various generated links. If you keep it without the prefix, some URLs will be wrong.

  • Keep controller routes as-is You do NOT need to change [Route("api/...")] attributes or conventional controller prefixes. PathBase sits in front of the entire app, so /api/auth/api/values would be wrong. Correct request is /api/auth/api/values, which is “/api/auth” (PathBase) + “/api/values” (your controller route). Don’t double-prefix routes.

  • Swagger JSON endpoint path With PathBase, the JSON is served at /api/auth/swagger/v1/swagger.json. Ensure:

    • app.UseSwagger() is after UsePathBase.
    • SwaggerEndpoint uses the full path including /api/auth.
    • If you view Swagger UI at https://localhost:44320/api/auth/swagger, the UI can fetch /api/auth/swagger/v1/swagger.json.
  • Anti-forgery and ABP Swagger UI script ABP’s Swagger integration injects abp.js to handle CSRF. With PathBase, the SetCsrfCookie endpoint will resolve correctly as long as App:SelfUrl and PathBase are consistent and the Swagger UI page is under the same PathBase.

  • If you also expose static assets under the same site Call app.UseStaticFiles() after UsePathBase so static files are served via /api/auth/… when requested from this host.

  • Common pitfalls that cause 404 in Swagger:

    • PathBase set but SwaggerEndpoint missing the prefix. Correct: options.SwaggerEndpoint("/api/auth/swagger/v1/swagger.json", ...).
    • Setting RoutePrefix to “swagger” while PathBase is “/api/auth”, then browsing https://localhost:44320/swagger (wrong). With RoutePrefix = "api/auth/swagger", browse https://localhost:44320/api/auth/swagger.
    • Changing controller route prefixes to include “auth” while also using PathBase, which doubles the segment.

Optional (only if you must run the UI at root /swagger while API is under /api/auth):

  • Keep PathBase("/api/auth").
  • Set options.RoutePrefix = "swagger" and options.SwaggerEndpoint("/api/auth/swagger/v1/swagger.json", ...).
  • You will browse Swagger at https://localhost:44320/swagger, but the JSON still resolves under /api/auth/… This is valid if you prefer Swagger at root.

  1. Solution ABP uses ASP.NET Core logging with Serilog pre-configured in the startup templates. By default:
  • Where to see logs during development

    • Console: visible in the HttpApi.Host output (dotnet run or VS output).
    • File: Serilog writes rolling files under a Logs folder in the host’s content root. Typical path:
      • src/YourProject.HttpApi.Host/Logs/logs-<date>.txt
      • If IIS Express is used, the content root may be under the IISExpress working directory; prefer dotnet run to keep logs under the project folder.
  • How to confirm or change the file location

    • Check appsettings.json (and appsettings.Development.json) in HttpApi.Host for Serilog configuration. The File sink path (or rolling file) controls where logs are written. Example keys:
      • "Serilog": { "WriteTo": [ { "Name": "File", "Args": { "path": "Logs/logs.txt", ... } }, ... ] }
    • Adjust path to an absolute or relative directory of your choice and restart the host.
  • Increasing verbosity to capture errors

    • In appsettings.Development.json, set MinimumLevel and per-source overrides, e.g.:
      • "Serilog": { "MinimumLevel": { "Default": "Information", "Override": { "Microsoft": "Warning", "Volo": "Debug" } } }
    • Restart the host to apply.
  • Production recommendations

    • ABP recommends using a durable sink (e.g., Elasticsearch, Seq, database) instead of plain files in production. Add/change Serilog sinks in appsettings.json and deploy with appropriate volumes/paths.
  • Quick checklist

    • Run HttpApi.Host with dotnet run and reproduce the issue; check Console and Logs folder.
    • Verify Serilog:WriteTo section exists in HttpApi.Host appsettings(.Development).json.
    • If no Logs folder appears, ensure the File/Async sinks are configured and the process has write permission to the folder.
