Remove or hide the client-side theme switcher
Clear persisted client preference so testing doesn’t revert to Dark
Prevent system/OS dark preference from applying
If you still see dark colors, verify CSS order

What’s happening
Definitive fix steps
Fully remove any previously downloaded/cached copies of the tool package to prevent a bad cache from being reused:
Force install from nuget.org only, no cache, minimal config:
If it still fails, install a specific version explicitly (this bypasses any ambiguity in service index resolution):

Root cause
Fix definitively by isolating sources
Uninstall and clear caches:
Create a minimal NuGet.config that only contains nuget.org and clears inherited sources:
Install using only that config and no cache:
If you still see nuget.abp.io or any other feed in the logs, you likely have a tool manifest or a global config injecting sources. Force ignore any failing sources and specify both options:

Clean up global configuration that injects failing sources

What happened
Fix steps
Ensure you uninstall any previously installed ABP CLIs:
Clear all NuGet caches:
Temporarily force nuget.org as the only source while installing:
If you have a NuGet.config (global or solution-level) that adds internal/private feeds, make sure they don’t shadow nuget.org or inject a failing source as first priority. Either:
If your environment enforces authenticated private sources, add --ignore-failed-sources to bypass them for this install/update:

Why it happens
What to do
using Microsoft.Extensions.DependencyInjection;
using Volo.Abp.Modularity;
using Volo.Abp.AspNetCore.Components.Web.Theming;
[DependsOn(
typeof(Volo.Abp.LeptonX.Shared.AbpLeptonXSharedModule) // keep your existing deps
)]
public class YourWebModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
// Ensure the DI can resolve your custom layout component
context.Services.AddTransient<CustomSideMenuLayout>();
// Tell the theme system to use your component as the application layout
Configure<AbpThemingOptions>(options =>
{
options.ApplicationLayout = typeof(CustomSideMenuLayout);
});
}
}
// CustomSideMenuLayout.razor
@inherits Volo.Abp.LeptonX.Shared.LeptonXTheme.Layouts.SideMenuLayout
@* your customizations here *@
If you are using multiple LeptonX layout variants (e.g., top, side), and you switch them dynamically, ensure you set ApplicationLayout accordingly (e.g., based on configuration) before first render, typically in ConfigureServices as above.
Clean and rebuild to avoid stale component resolutions:
Stop the app
Delete bin/obj of UI projects
Rebuild and run

Root cause
Mandatory checks and fixes
Forwarded headers and cookie security behind nginx
Data Protection key ring must be shared across every server that issues or reads cookies
SameSite for all OIDC correlation/nonce and auth cookies
WebAssembly sub-app authentication for Blazor Web App
CORS and RedirectAllowedUrls
Cookie path and domain
WebSocket support (for Server interop and signalr features used during SSR/interactive server)
Place app.UseBlazorFrameworkFiles (if hosting WASM assets) before app.UseStaticFiles when applicable
Do not rely on AddAuthenticationStateSerialization to fix this
Concrete checklist you can apply now
Answers to your specific questions
Minimal code/config examples
Server (Program/Module order hints):
public override void OnApplicationInitialization(ApplicationInitializationContext context)
{
var app = context.GetApplicationBuilder();
var env = context.GetEnvironment();
if (!env.IsDevelopment())
{
app.UseForwardedHeaders(); // before auth
}
app.UseCorrelationId();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthentication();
app.UseAuthorization();
app.UseConfiguredEndpoints();

Cookie settings:
services.AddAuthentication()
.AddCookie("Cookies", options =>
{
options.ExpireTimeSpan = TimeSpan.FromDays(365);
if (!env.IsDevelopment())
{
options.Cookie.SameSite = SameSiteMode.Lax;
options.Cookie.SecurePolicy = CookieSecurePolicy.Always;
options.Cookie.HttpOnly = true;
}

nginx (add upgrade headers if needed):

proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header Host $host;

services.AddAuthentication().AddJwtBearer(options =>
{
options.Authority = configuration["AuthServer:Authority"]; // e.g. https://auth.my-domain.com
options.RequireHttpsMetadata = true; // or false for local dev
options.Audience = "AdministrationService"; // must match your token’s aud
});
Symptom when missing/incorrect: application-configuration returns isAuthenticated = false and grantedPolicies empty even with a token. This is a confirmed, common root cause in ABP (see the support ticket in Sources).
If you migrated from IdentityServer to OpenIddict (ABP 8+), align the OpenIddict configuration
PreConfigure<OpenIddictServerBuilder>(builder =>
{
builder.SetIssuer(new Uri(configuration["AuthServer:Authority"]!)); // https URL
});
- When terminating TLS at a proxy, either:
- Forward the scheme correctly (X-Forwarded-Proto) and enable forwarded headers in all apps, or
- Force scheme to https on the server:
app.Use(async (ctx, next) =>
{
ctx.Request.Scheme = "https";
await next();
});
- If your backend listens on HTTP and you can’t forward HTTPS, disable the transport security requirement:
if (!Convert.ToBoolean(configuration["AuthServer:RequireHttpsMetadata"]))
{
Configure<OpenIddictServerAspNetCoreOptions>(o =>
{
o.DisableTransportSecurityRequirement = true;
});
}
- Make sure discovery JSON (/.well-known/openid-configuration) returns HTTPS URLs. If it returns HTTP, front-ends (Angular/OIDC libs) will ignore it and no valid token flow will occur.
Confirm the bearer actually reaches the endpoint
Multi-tenancy header/host checks (if applicable)
Token issuance scope and client configuration (OpenIddict)
Logging to confirm
If you implement the audience fix and ensure the discovery/issuer are consistent HTTPS values (or correctly forwarded), the application-configuration endpoint will include:

What happens by default:
Why: OIDC single logout is a separate step. To sign out of the external Identity Provider (Microsoft Entra), the client must call the Entra “end session” (sign-out) endpoint with appropriate parameters. ABP/OpenIddict doesn’t automatically perform an upstream IdP logout. Some IdPs also restrict third-party initiated sign-outs.
What to do:
If you want to also sign out from Microsoft Entra:
Example (Blazor WASM override of the Authentication page):
// MyAuthentication.razor
@using Microsoft.AspNetCore.Components.WebAssembly.Authentication
@using Volo.Abp.DependencyInjection
@inherits Volo.Abp.AspNetCore.Components.WebAssembly.LeptonXTheme.Pages.Authentication
@attribute [ExposeServices(typeof(Volo.Abp.AspNetCore.Components.WebAssembly.LeptonXTheme.Pages.Authentication))]
@attribute [Dependency(ReplaceServices = true)]
<RemoteAuthenticatorView Action="@Action" />
// MyAuthentication.razor.cs
public partial class MyAuthentication
{
protected override void OnInitialized()
{
if (Action == "logout-callback")
{
// 1) After app logout completes, sign out from Entra too:
var postLogout = Uri.EscapeDataString(NavigationManager.BaseUri.TrimEnd('/')); // e.g. https://yourapp/
var tenant = "your-tenant-id-or-common";
var entraLogout = $"https://login.microsoftonline.com/{tenant}/oauth2/v2.0/logout?post_logout_redirect_uri={postLogout}";
NavigationManager.NavigateTo(entraLogout, forceLoad: true);
return;
}
}
}
Important:
- Ensure post_logout_redirect_uri is configured in your Entra app registration.
- Use a fully qualified HTTPS URL.
- If you want to send users back to login immediately, set post_logout_redirect_uri to your app root (which is [Authorize] protected) or to /authentication/login.
builder.Services.AddOidcAuthentication(options =>
{
builder.Configuration.Bind("AuthServer", options.ProviderOptions);
options.ProviderOptions.AdditionalProviderParameters.Add("prompt", "select_account");
});
- This does not sign out Entra but prevents silent re-login.
