"Direct Connection Unavailable"
When i try to connect to a friend's Plex server over my WIfi at home i get this error on my Plex App "Direct Connection unavailable" It fails to connect, then when i try to connect again it does work but says indirect.
If i turn my Wifi off on my phone and connect to him over the 4G data it works fine. So i know its nothing to do with his end, it must be my router\firewall.
Does anyone know what i need to do, I'm guessing I need to open a port up over to his IP?
Cant find anything though on google that's fits my problem.
