Unstable running of standalone galaxy setup as Azure App Service

[kdudani-tibco]

Dear Team,

I am trying to run standalone galaxy setup as a docker container inside Azure App Service

However, I am able to see with the docker logs the docker container is spinned up very well and the instance is started successfully. But when I try to hit the URL, I always keep getting 403 Forbidden error (nginx/1.14.0 (Ubuntu).

I tried running with 20.09v, 20.05v and observe this forbidden page error.

P.S.: I do not see this error when I ran of version 18.05 (which is deprecated and no longer maintained). So this proves that the setup works, however not with the latest versions.
P.N. : I am first trying to run stateless docker service in-order to explore if it is possible to run on Azure app service.

Can you please guide me, over what extra settings do I need to enable in-order to run this setup successfully as Azure app service ?
