Getting HTTP Error 500.30 after successful publishing to Azure

Questions
1

I have created my first Umbraco 9 VS Project.

When publishing the application to Azure everything seems to be successful until I run the page then I get:

HTTP Error 500.30 - ASP.NET Core app failed to start
Common solutions to this issue:
The app failed to start
The app started but then stopped
The app started but threw an exception during startup

Troubleshooting steps:
Check the system event log for error messages
Enable logging the application process’ stdout messages
Attach a debugger to the application process and inspect

I had the same problem. For me it was the IIS_IUSRS permissions.

Additionally, have you checked the following?

  1. Environment configuration
  2. The database connection string is correctly placed and the database connection is valid
