Plex & "Looking for servers..." - hint: check UPnP

[bernieTB]

All, just adding this post for posterity: if your Freenas is sitting behind a firewall (like in my case a pfSense) and you're not getting past the "Looking for servers..." then check whether UPnP is enabled...

I've been cursing this thing for hours not figuring out why this wouldn't work.

I've enabled UPnP (on pfSense) and then plex found the server. Once it started scanning my libraries I switched it off again.
