Server suddenly offline

[robinsee]

Hello all,

Been using Jellyfin for months with no issues, watched it last night then this morning the server is offline. local works through browser but phone and other devices are dark citing server offline.

This is my first time posting, looking to understand what i need to look for in diagnosing.

I tried restarting the server already.
Can someone assist?

It looks like there are two active interfaces on your server? Is one an Ethernet connection and another a WiFi connection through a repeater?

Code:

[2025-04-18 10:31:10.618 -04:00] [INF] [1] Jellyfin.Networking.Manager.NetworkManager: Filtered interface addresses: ["192.168.56.1", "192.168.1.190", "127.0.0.1"]

You have both a .1 and a .56 address. Is one of them a VPN or something?

You said you don't have a repeated, but is your WiFi setup some sort of mesh network?

I recall another user with a similar issue that did have a mesh router setup. There was some setting that pushed clients on one of the mesh nodes, vs the main node, to a different subnet. Which would line up with the server having two IPs.

no mesh network, but im on fiber and it does have a type of router ive seen people have issues with on Jellyfin

upon setup i had issues and ran into a Reddit post that said Jellyfin doenst work with this router, then after days of trying it just....worked.

i was wondering if it was a band issue with me moving to another room. but no mesh or other nodes, just a single router.

the ATT BGW-320

to be clear i havent touched any settings on the BGW320 to get Jellyfin to work, i dont think

would this be called Double NAT?

i found a Reddit post on it. it sounds like this model has numerous issues and a bypass is the best solution

That is definitely possible. But I've only had to deal with that when I used my own router in conjuction with the ISP provided router (before I figured out how to setup bridge mode).
