I had a working solution in ABP Suite. Everything was fine during the ABP Trial period. Last monday the license expired while i was talking with your sales person Elif, and although she agreed to extend the trial period, i was not able to run the solution anymore.
What happens: I can start ABP Studio I can start the docker container for Redis I cannot start the AuthServer. It fails with error -42 and then it restarts. I cannot start my HttpApi.Host, same problem
Mainwhile I already paid for the license, and the production license is active now, but nothing changed. Error stays I already removed the license and logged in again, no success
My colleague has the exact same problem since the exact same time, so it must be something with the license that expired.

- This is not an ABP Framework / AuthServer (OpenIddict) license issue. An ABP commercial license expiring does not make your
*.AuthServeror*.HttpApi.Hostprocess exit with a special code. - In ABP Studio, “exited with code: -42” is a pattern typically seen when the process is killed externally (security software / endpoint protection / corporate policy), not when the app throws an exception. That also explains why you don’t see any .NET exception/stack trace in the output and why it suddenly started for multiple colleagues at the same time.
Do this to fix it (works in corporate environments)
- Run the AuthServer outside ABP Studio to see the real termination reason
- Open a terminal in the AuthServer folder and run:
dotnet run --project .\src\TVRS.AuthServer\TVRS.AuthServer.csproj- If it still exits with
-42without a .NET stack trace, it’s being terminated by something external (AV/EDR/policy).
Whitelist ABP/Studio network endpoints in your security software
- If your company uses Kaspersky/Defender/EDR, ensure
abp.ioand subdomains are allowed (this is a known class of issues with ABP Studio/network communication, and it can indirectly break the “run” experience):*.abp.io(coversaccount.abp.io,nuget.abp.io, etc.)
- If your company uses Kaspersky/Defender/EDR, ensure
Verify ABP account endpoint is reachable from the .NET runtime (not just browser)
- Run:
[System.Net.Http.HttpClient]::new().GetStringAsync('https://account.abp.io/.well-known/openid-configuration').Result- If this fails while the browser works, it’s almost always proxy/SSL inspection/AV interference.
- If you need an official/support action (license/account side)

I did step 1 It stops with a license error [19:33:14 ERR] ABP-LIC-0018 - EtVHKXrqlGVmoMegUvB: Your trial period has ended! - Please contact to license@abp.io to purchase a license.
But I have a production license.
