Docker Compose on Azure App Service randomly fails and doesn't work again

Question

I setup a docker compose with a reverse proxy on the nginx side. It seemed to have worked at first but after adding some app settings, it stopped working. I removed the app settings and it did not fix it.

I had this problem happen on 3 different apps. I know it is a preview feature but I don't see any other way other than using a VM which would add management overhead that I am trying to avoid.

Here is my docker compose:

version: "3.8"
services:
  webapp: 
    image: resource_name.azurecr.io/webapp:latest
    ports:
      - "80:80"
  wordpress:
    image: resource_name.azurecr.io/wordpress:latest
    restart: always
    ports:
      - 8080:80

At first, it loads the containers and the reverse proxy even works!

I have two theories.

1. Updating the app settings bricks it and can't recover it.
2. Adding an outbound v-net does it.

I couldn't pinpoint what does it.

Here is the error in the logs: Failed to load container logs: Resource containerlog of type text not found

It was the Outbound V-Net. Removing it resolved the issue.
