ReassuredTiger98 this is simply because the nginx is configured with the fileserver address and fails because the address itself is invalid - I think that if you override this address with something valid (even though that's not a proper fileserver) the error should not appear. Try setting the NGINX_FILESERVER_ADDRESS
env var in the docker compose for the webserver with something like http://apiserver:8008
I am currently on the move, but it was something like upstream server not found in /etc/nginx/nginx.conf and if I remember correctly line 88
It should be possible 🙂 - what error are you seeing?
I'll take a look - if you get a chance to paste the exact error that would be great 🙂
