Hi @ViktorGeorgiev7
I would start with the Troubleshoot category in Diagnose and solve problems blade. This will give you deeper insights into the logs your application is producing during startup. The default project template in Visual Studio should produce logging that this detector can pick up. If you don't see anything, you can refer to Troubleshoot ASP.NET Core on Azure App Service and IIS | Microsoft Learn to configure your app service to get that logging into these detectors. If you aren't able to resolve the issue, please feel free to drop the errors your app is producing in a comment below.
