Jellyfin not discoverable

[merulius]

I'm a mac and IOS user and I can't get Jellyfin 10.9.3 to work on Ubuntu server and be seen by Naim app on Iphone. Something to do with the change in DLNA in 10.9.3.

Worked fine in previous version.

Only running one subnet = Default on unifi network.

edit: this message on jellyfin logs seems relevant
[2024-05-29 23:59:18.280 +00:00] [ERR] Error sending socket message from "192.168.1.14" to "239.255.255.250:1900"

DLNA is now an optional plugin and isn't installed by default. Also, port 1900 is also used for service discovery. Make sure UDP port 1900 is open in the host firewall.

sudo ufw allow 1900/udp

dashboard → networking, Explicitly setting the LAN address can solve this problem.
For example: 192.168.1.0/24
