I opened a port on mullvad, ran an iPerf server on said port, and the port was reachable. I closed the iPerf server, opened Emby with the public http set on said port, and Emby doesn't want to work. I've tried setting the External Domain to the IP mullvad was using. I've tried restarting. Ive looked at all the other servers running and none of them use the port opened for mullvad.
Mullvad is a vpn, by the way
