  1. Solution

  • What exit code -42 means in ABP Studio

    • In ABP Studio, “exited with code: -42” indicates the target app (e.g., HttpApi.Host, Web.Public) terminated unexpectedly soon after start. It’s typically caused by an unhandled startup failure (ports, configuration, missing env/deps), not by ABP Framework itself. The Solution Runner then keeps attempting restarts.

  • Likely causes from your log and setup

    • HTTPS port conflict or reservation: Studio probes health endpoints at 44302/44383 and the UI at 44382. If these ports are blocked, reserved by HTTP.SYS, or fall into Windows excluded port ranges, the app can start then crash.
    • Certificate/HTTPS binding issues: Kestrel can fail when the dev cert is missing/untrusted on new machines.
    • PostgreSQL connectivity: With Separate Tenant Schema + initial migration run, any wrong connection string or unreachable DB can kill the host at startup.
    • NuGet feeds/tooling: If global NuGet.config forces an unreachable private source for tools or packages, builds can succeed partially but runtime may fail later during dynamic restore.
    • Environment differences between machines: Missing .NET SDKs required by the solution, or prereqs not present.

  • Fix checklist (perform on every affected machine)

    1. Verify .NET SDKs
       • Install the SDKs targeted by your solution (check global.json and csproj TargetFramework). Ensure dotnet --info shows them.
    2. Clean/restore/build once outside Studio
       • From the solution folder:
         • dotnet clean
         • dotnet restore
         • dotnet build -c Debug
       • If build fails, fix errors first.
    3. Ensure HTTPS dev certificate is installed and trusted
       • dotnet dev-certs https --clean
       • dotnet dev-certs https --trust
    4. Free or remap ports
       • Check excluded/occupied ports:
         • netsh interface ipv4 show excludedportrange protocol=TCP
         • netsh http show urlacl
         • netstat -ano | findstr :44382
       • If 44302/44382/44383 are in excluded ranges or used, change ports:
         • In each app’s appsettings.json (or launchSettings.json), change Kestrel:Endpoints:Https:Url (and Health endpoints) to free ports, or in ABP Studio Runner profile set different ports, then run again.
    5. Trust local hostnames
       • Make sure you browse the exact HTTPS URLs Studio opens. If the browser prompts for cert trust, accept it.
    6. Verify PostgreSQL connectivity
       • Confirm the default connection string in your HttpApi.Host appsettings.* points to a reachable PostgreSQL instance with correct credentials.
       • Test with psql or a client using the same host, port, db, user, password.
       • If you use separate schemas per tenant, ensure the database exists and the migrator was executed successfully.
    7. Re-run the DbMigrator
       • From src/OPUSNova.DbMigrator:
         • dotnet run
       • Fix any migration/connection errors it shows.
    8. Check global NuGet config for unreachable private feeds
       • If you have a company NuGet feed configured globally that is not reachable on some machines, it can break tool/package restore. Remove or disable it temporarily in %AppData%\NuGet\NuGet.Config or related config files and keep nuget.org active.
       • This exact issue was reported and fixed by removing a stale private feed from NuGet.Config.
    9. Start projects manually to see first exception
       • Run OPUSNova.HttpApi.Host from command line:
         • dotnet run
       • Observe the first thrown exception/stack trace in the console; it often reveals the exact root cause that Studio abstracts as exit code -42.
    10. ABP Studio prerequisites
    • Ensure ABP Studio CLI is installed and can run:
      • abp cli version
    • If it fails due to NuGet source issues, fix NuGet.Config as in step 8.

  • Notes for Blazor WASM + Public Website profile

    • The Blazor (WASM) and Public site rely on the HTTP API host being up. If the host crashes (-42), both health checks will fail and Studio restarts them. Fixing the host’s startup error usually resolves the rest.

  De acuerdo a las recomendaciones ejecute el comando: dotnet run --project src/OPUSNova.HttpApi.Host/OPUSNova.HttpApi.Host.csproj

  Como resultado manda esto: aparece ABP-LIC-0018: “Your trial period has ended!”. Eso hace que el proceso termine inmediatamente y ABP Studio muestre “exited with code: -42

  Contexto: Asunto: Urgente: Problema de ejecución de aplicación para usuarios migrados de licencia Trial a Business

  Estimado equipo de soporte,

  Solicitamos su asistencia urgente con un problema de licenciamiento que afecta a tres de nuestros desarrolladores.

  A continuación, detallamos la situación:

  Licencia Trial: Inicialmente, operamos con una licencia Trial para 3 desarrolladores. Dicha licencia expiró el 10 de noviembre de 2025.

  Nueva Licencia Business: Antes del vencimiento, el 29 de octubre de 2025, adquirimos una nueva licencia Business.

  Migración de Usuarios: A la licencia Business se incorporaron los 3 desarrolladores que usaban la licencia Trial (utilizando sus mismos correos electrónicos) y se añadieron 2 miembros nuevos al equipo.

  El Problema: Los 3 desarrolladores originales que fueron migrados de Trial a Business no pueden ejecutar la aplicación. Sin embargo, los 2 desarrolladores nuevos, que no tuvieron licencia Trial, sí pueden ejecutar los proyectos sin inconvenientes.

  Acciones Tomadas: Los 3 desarrolladores afectados ya realizaron un cierre de sesión (Logout) y un nuevo inicio de sesión (Login) para intentar forzar el reconocimiento de la licencia Business, pero el problema persiste.

  Esta situación está afectando nuestra capacidad de desarrollo y requerimos una solución a la brevedad posible.

  Quedamos atentos a su pronta respuesta.

  Saludos cordiales, Jorge Torres

  Can you log out and log in again using the abp cli?

  > abp logout
  
  > abp login
   Press Enter to open your browser to login...
  Successfully logged in as 'maliming' with the organization 'Volosoft Bilişim A.Ş.'.
  

  After that, create a new project and copy the new project's NuGet.Config and appsettings.secrets.json files to your old project.

  Then, clear the local NuGet cache.

  dotnet nuget locals all -c
  

  Rebuild your project with worlds.

  Thanks.
