I've used Plex with no issues over the last 2 years and out of the blue videos no longer will play on any of my devices. I'm running El Capitan 10.11.5 on Mac with no play back issues. I haven't made any changes to any of my devices for this error to occur. I installed Plex on my mac to try and clear up any issues and singed out and in on all devices, but no luck. My media library shows up on all my devices put videos will never load and play.
Any ideas?
