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?
