Hello Görkem Can Süleymanoğlu,
Welcome to the Microsoft Q&A and thank you for posting your questions here.
I understand that you need more information about Azure Credit, Azure App Service and Windows Entra for your hosting.
Firstly, the HTTP 500.30 error typically means your app failed to start. Given the requirement to use Windows Entra authentication, the error could result from:
- Misaligned settings in Azure App Service or the application code.
- Missing dependencies or mismatched frameworks.
