SOLVED: Can't find server from LAN

[vt-fin]

This is on Linux, jellyfin running on Docker. Had to reinstall the system and set up JF again from backups.

Everything seemed fine setting up, but then I go to <host>.local:8096 in the browser and this comes up:

"Select Server
No servers have been found using the automatic server discovery."

If I try to connect it shows "We're unable to connect to the selected server right now. Please ensure it is running and try again.".


Same thing happens if I go to the dashboard using the IP address, and clearing cache/cookies does nothing.


The weird thing is that if I enable "Allow remote connections" then everything works fine. Since I haven't forwarded the ports, I guess it would be safe to leave it on, but I would prefer having it set up properly.


Any ideas?


UPDATE: disabling IPv6 as per here fixed it.

Try clearing your browser cache.

Also, did you backups include both the docker compose and all the jellyfin data files?

[vt-fin]

Tried that, but no change.

Yeah, the config is in a volume, which I had backed up and restored. Since enabling that "Allow remote" option makes everything work normally, I would think the data is ok?

[TheDreadPirate]

"Allow remote connections" only tells the Jellyfin to allow connections from IPs that are not in the defined LAN address spaces. Which can be on the same LAN if you have multiple subnets. Do you have an non-standard values for your LAN networks? Did your host IP address change?

I came across this: https://github.com/jellyfin/jellyfin/iss...2118823950

Not sure why, but disabling IPv6 also fixed it for me (others were suggesting disabling IgnoreVirtualInterfaces as well, but didn't need to).

That issue is now closed, but it was not clear why it needs to be disabled. Is it disabled by default? If not, then maybe this should still be looked into.
