I've been using PlexConnect without issue for the past 6 months, but suddenly I can't get it to work anymore. I can still access my Plex locally or remotely via the Android app, but every time I tried to use my aTV, after a moment it says there are "No Plex Library Sections Available".

I tried changing the settings.cfg to force my local IP to see if that was causing the problems. I've also tried reinstalling PlexConnect, rebooting my computer, aTV, and my router to no avail. I'm stuck watching now via my Chromecast, but my housemates are technically inept making that a less than ideal solution for them.
