Plex has stopped working and I can not play anything every think keeps coming up with Play Back Error - Conversion failed. The transcoder failed to start up.. if I try via the apple tv or even dirctly on the plex server from localhost page via chrome.

I’ve rebooted the server a number of times and same issue .. have had zero issue and now this anyone have any ideas why it would have just stopped working is there a issue with a recent update ?

Found the in the console
