Well I already have jellyfin running in a container, just have to figure out how to get mum's TV to work with it I guess
log in on a local IP and not the network name and it's working again. but I'll be moving to jellyfin from now
Yes. You only need to pay if you’re connecting via their relay or trying to use the remote hosting functionality. But since a VPN would land you inside of the network, you’d be fine. You’d probably need to dig into the plex settings to specify that the VPN subnet is LAN traffic. But after that, you should be good.
