Hi,
I've recently tried to install PlexConnect on my friends laptop. (To use with ATV3 5.2.1)
I installed Plex Media Server (Haven't done anything with it - when i open it it opens a web app in safari so I assume it's fine)

Downloaded the latest PlexConnect and run it in Terminal.
Changed the Apple TV's wifi settings to the laptops
But when i open the trailers app i get the message "Plex Media Server" (As the header) and underneath that "Unknown Error"

Any help is appreciated.
Cheers!
