Cannot connect to server from iPad



I have the Plex server in a docker container on unRAID in bridged mode with the ADVERTISE_IP variable set. The configuration was working fine until very recently, when I discovered that both 12.9 and 9.7 iPad Pro cannot connect to the server. Connecting from an iPhone seems to be working fine, all devices have the latest update from the App Store.
Peeking into the logs via iOS Console, it seems that the iPads are trying to connect via the internal address of the docker container instead of the one specified in ADVERTISE_IP. Can you advise how to resolve?


Same issue here.
