By default Drupal's proxy settings do not parse Forwarded headers (*IP etc) which is what we use for Anubis since PHP becomes an upstream. When not done, Drupal will see only the Docker NGINX Container's IP address and ignore forwarded headers and thus interfere with IP embargo bypass logic (good thing is, no bypass will happen so nothing is unsecured at all!)
The fix is easy but requires some defaults/docs. DevOps is always a "suggestion". Please be aware of what you are doing with using the guides.
