SOLVED: Nginx Reverse Proxy Connection Issue

[kensible]

I am using the latest linuxserver Docker image for Jellyfin. I followed the official guide (here) for configuring Nginx with Jellyfin. I can access the Web UI through https://jellyfin.mydomain.com, but I can't connect to my Jellyfin server. I get an error message that says the server may be offline. However, I am still able to access the server on my local network, just not externally.

Nginx or Nginx Proxy Manager?

Can you share screenshots of Nginx? Did you select HTTPS for the proxy pass scheme? If so, it should be http.

Nginx Proxy Manager. I attached some screenshots to the original post. I configured everything using the Web UI for the Nginx Proxy Manager, following the relevant section of the Jellyfin documentation. I am able to access the Jellyfin page externally (not on my local network), but I see the server selection screen instead of the login screen. Additionally, I verified that all of my other Docker containers are visible externally with SSL encryption, so I figure that there must be a Docker networking issue or something between Nginx Proxy Manager and the Jellyfin server (?)

I figured out the problem! I needed to enable the “allow remote connections to this server” setting under Advanced -> Networking.

Sometimes it is the simple things. I made this exact mistake and spent more time troubleshooting that I'd like to admit.
