:( Application Error If you are the application administrator, you can access the diagnostic resources.

Hi Sujith Mohan,

In addition to Alex Burlachenko response,

1. Go to Azure Portal > App Service > Restart to clear any temporary glitches. If the error persists, navigate to App Service > Diagnose and solve problems and clear the server-side cache.
2. In Azure Portal > Configuration, ensure all environment variables are correctly set, including connection strings, keys, and any settings related to Managed Identity or User Delegation SAS for Azure Storage access. Misconfigured settings are a common cause after deployment.
3. Verify the startup command under Configuration > General settings. Ensure it's pointing to the correct entry point (e.g., dotnet <YourApp>.dll for .NET Core apps). Incorrect startup commands often lead to application errors.
4. Since Kudu is inaccessible, use Azure Portal > App Service > SSH to access the container. Check logs under /home/LogFiles for detailed error messages. This helps identify startup or dependency issues. (refer below link)
5. If no configuration issues are found, redeploy the application to ensure the deployment artifacts aren't corrupted. After redeployment, restart the App Service.

Hi Sujith,

Sorry to hear about the issue with your App Service. Check Deployment verify that the deployment was successful and all files were correctly uploaded. Diagnostic Logs access the diagnostic logs from the Azure portal under "App Service logs" to identify any errors. application Settings ensure that all necessary environment variables and connection strings are correctly configured. Restart App Service sometimes a simple restart can resolve temporary issues. Kudu Access ff Kudu is inaccessible, try accessing it via the URL: https://<your-app-name>.scm.azurewebsites.net. Log Stream if Log Stream isn't working, check the "Log stream" section in the Azure portal for real-time logs. If the issue persists, consider redeploying or reaching out to Azure Support for assistance.

Hope this helps!
