    Thanks for asking question! HTTP Error 500.30 – ANCM In-Process Start Failure” is moreover a generic error. To know more information about the error Go to Azure Portal > your App Service > under development tools open console. We can run the application through this console and thus visualize the real error that is causing our application not to load. For that put, the name of our project followed by “.exe” and press the enter key.
