Android phone can't connect

[bahnstern]

Hey folks, at wit's end here. Trying to get my Jellyfin server to work with my android phone (Pixel 9 Pro, Android 14). It worked when I originally set up the server, and then again briefly when I updated to V10.10.0 today, but now cannot connect via web browser or official jellyfin app. The official Jellyfin app gives me an error: "Unable to reach server" and web browsers (have tried both Chrome and Firefox) just time out. I also unable to connect to my Heimdall install from my android phone (also running in a Docker container). I am able to connect to both cockpit and my foundry server, neither of which are containerized. 

Setup:
Jellyfin 10.10.0 running in a Docker container
Beelink Mini S 12th gen (Alder Lake N100, 16 GB RAM, 1TB SSD)
Ubuntu 24.04.1 LTS
Connected to NordVPN Meshnet (connection works through my desktop PC and Chromecast, both on Meshnet)

Things I've tried/checked:
- Made sure remote connections are enabled
- Tried both .nord address (http://username-atlas.nord:8096) and meshnet IP address
- Disabled IPv6
- Restarted the Jellyfin container
- Made sure ufw is running and 8096 is enabled
- Cleared the cache on the android app and tried connecting again

Any thoughts?

Can you provide your full jellyfin log via pastebin?

Here ya go..

Can you restart your jellyfin server and then share the log again? I want to see the logs for a server startup.

[bahnstern]

Here is the log with the restart.. restarted at 1343.

Is your VPN part of the same docker bridge network? Or are you publishing port 8096? Can you share your docker config for Jellyfin?

[bahnstern]

These questions are starting to get into what I suspect I messed up, as I'm having issues with both docker containers (jellyfin, heimdall) on android devices.

Is your VPN part of the same docker bridge network?
- if it requires manual config, then probably not.. honestly getting beyond my knowledge, still learning here

Or are you publishing port 8096?
- see above

Can you share your docker config for Jellyfin?

You're publishing port 8096. So the "host" IP:8096 should work.

I'd also need to see your heimdall config. Strange that your browser and Android TV clients work.

Nm, I didn't scroll down. Never used Heimdall. Is Heimdall also your reverse proxy?

[bahnstern]

Ahh, gotcha. Yeah, that's what's throwing me off. Browser access from my desktop and laptop work through the Nord Meshnet, but the Android TV is just accessing the server on the local network rather than meshnet. Android access also briefly worked with the current configuration.

Heimdall is simply a homepage that you can use to set up links to all the services you are hosting on your server. I only mentioned it as I also can't connect to it from my android phone. My suspicion is that I messed something up on the docker side of things because my non-containerized services (FoundryVTT and Cockpit) work just fine with my android phone.

My NordVPN install is also not containerized. I'm using meshnet in lieu of a reverse proxy. Its a peer-to-peer mesh network, so should be acting like a LAN. Very similar to Tailscale from my understaning. https://www.cnet.com/tech/services-and-s...-your-vpn/

On your phone, what address are you using to connect? Your server's meshnet IP? A hostname?
