I have a debian linux host with docker installed on it. I followed the guide here: https://join-lemmy.org/docs/en/administration/install_docker.html

Changes that I made:

• I used a sub folder called lemmy in my containers area rather than /lemmy
• I copied the nginx.conf file from https://github.com/LemmyNet/lemmy/blob/main/docker/nginx.conf to my lemmy folder and ran a docker-compose up.
• I changed the proxy service ports to 17008 (other service runs on 80) and 17003 (instead of 443).

I changed absolutely nothing else. No hostnames, no passwords. Nothing. The docker logs show it up and running.

Docker ps shows the instance fine too:

I've tried accessing http://<hostname>:17008, https://<hostname>:18003. I've tried setting my local hosts file for hostname "lemmy" to that server IP and accessing via http://lemmy:17008 and https://lemmy:18003

Is there something obvious that I'm missing?
