I restarted my gitlab hosted on docker and then suddenly nginx cant connect to it anymore

I restarted my gitlab hosted on docker and then suddenly nginx cant connect to it anymore.
When I do docker exec inside the container and do localhost:8080/gitlab it gives me back a sign in result.
This is netstat INSIDE of my gitlab_web container:

It should set take the request when we go to apprepodev.ddnyi.local/gitlab → forward it to nginx → forwards it our linux server (10.2.1.85:800) → sends it to docker. Isnt this the expected behavior?
Thank you for all help!
I tried changing the ports to 800->80 but still doesn’t work.
