Hi
Got this warning spamming my logs for ages. The few threads I've read about it are symptomatic of a network issue, but I have strictly zero issues with my config.
My network topology
192.168.1.* = LAN
192.168.2.* = DMZ
192.168.2.4 = Webserver (where jelly runs in docker)
192.168.2.10 = Frontdoor (caddy reverse proxy + auth and security stuff)
All servers are Ubuntu and all services are docker.
Logs of 192.168.1.3 is my monitoring server that retrieve Jellyfin /metrics (Prometheus)
Logs of 192.168.1.50 is my computer accessing Jellyfin web
Everything works.
Jellyfin (docker) working fine and is reachable from all machines in the DMZ where it lies, from LAN, and from WAN.
I'd like to get rid of this warning spam in my logs but all attempts failed so far. I've notably added LAN/DMZ/Docker networks to the LocalNetworkSubnets and that doesnt change anything.
Note that there's nothing exotic specified in my docker-compose for Jellyfin network, it just uses default bridge driver.
Network file
I have no error with my config.
And according to me, this warning message is just triggered for nothing in my case, and is thus useless spam.
