DDNS/Reverse Proxy issue

[saiyogi2k]

Hi, i use DuckDNS and nginxproxymanager to connect to jellyfin externally. it works most of the time but sometimes randomly it says unable to connect, while it still works via local networks. I try other services such as jellyseer at the same time and they seem to work with the same configuration. Only jellyfin acts up randomly and seems to get fixed in a while. Anything help would be appreciated on the issue.

Recent logs when i wasn't able to connect to jellyfin: https://pastebin.com/WtJ3jM9v

What client is having issues? An Android phone?

And what version of Jellyfin are you running? Looks like 10.9.6.

I am using 10.9.10 on debian 12. When its not working, its all clients. My browser and phone and jellyfin media player.

Is this a docker install or just a plain apt package install? Not including the docker IPs, I see serveral 192.168.###.### IPs. How many active interfaces do you have? Or VPNs.

Unrelated, it looks like you had a client that has an expired token that is constantly pinging the server. Though it looks like you logged them out and back in near the end of the log.

its a plain install. I dont have any vpn's running. Idk about others. i try to log in via the reverse proxy dns via local network and my mobile data both didnt work but it worked when i entered the ip:8096. Domain started working again now. What i dont understand is other services work even when jellyfin dosent. i have jellyfin and jellyseer exposed via 2 different DuckDNS domains and both behing nginxproxy manager. the jellyseer domain works even when jellyfin's is not working.
Also can you please explain what an expired token is?

Edit: i dont know if its relevant but i have npm, duckdns ipupdate and jellyseer all in docker. I had this issue even when jellyfin was in docker but i did a plain install now since i ran into some issues with transcoding with NVIDIA GPU in docker.

In Jellyfin, can you go to Dashboard > Network and enter a specific address for Jellyfin to bind to. You will need to restart Jellyfin to apply this change.

By default Jellyfin binds to all available interfaces and I'm wondering if sometimes Jellyfin is sending traffic on a different interface than it was received on.

You mean something like this? I have already done this. I did this since i had the same issue before. tried it but didn't change anything.

Negative.  This field.

   

Since Jellyfin seems to think there are a bunch of interfaces, I'm wondering if it isn't consistently sending responses on the same interface they were received on.  By setting this interface, Jellyfin will only use the interface(s) you've defined.

I have addded my local ip (192.168.100.108 ) to that field. Will update this thread if the issue persists. Thanks a ton.
