Discovery on docker

[Eric Mako]

Hello, I used the JELLYFIN_PublishedServerUrl=192.168.X.X and network_mode: 'host' lines in my docker compose, but the applications do not find Jellyfin I have to manually enter the server address

Is this normal?

[TheDreadPirate]

Are ports 1900 and 7359 open on the host?

[Eric Mako]

It's on my local network so it should work right? I don't have this problem when installing on bare metal

[TheDreadPirate]

The host's firewall (not the router) needs those ports open.

You also don't need the JELLYFIN_PublishedServerUrl set if you are using host networking.

[Eric Mako]

Oh I thought I had to use this line

# Optional - alternative address used for autodiscovery
environment:
- JELLYFIN_PublishedServerUrl=http://example.com

How should I set the host firewall? I never had this problem with the bare metal installation, it directly broadcast the server to the clients

What distro are you using?

[Eric Mako]

Debian 12

[TheDreadPirate]

Does Debian use UFW?

sudo ufw status ?

If Debian does use UFW it would be

sudo ufw enable
sudo ufw allow 8096
sudo ufw allow 7359
sudo ufw allow 1900

ufw is not installed, I'm trying to add the ports directly in docker compose and removing 'host' before installing ufw
