iOS airplay issues help

To keep it short and sweet my issue is that I can airplay to my Apple TV 3 without issue from all of our cellphones and tablets running iOS except for one iPhone 5c running 10.3.3 with the latest plex on it. Basically once I try to initiate the airplay I get the ring circling forever on the screen and in the background my entire media server has crashed and the only way to fix it is to reset the computer the server is running.

Any way to solve this issue? So far I’ve uninstalled plex on said iPhone and reinstalled with no results.
