I am forever getting "There was an error communicating with your Plex media server, make sure it's turned on and accessible and try again" I can browse the Movie folder and see all the metadata but when I start playing it, that's when the message appears, so I went to the Sever and it's running ok, I can even see the activity icon showing the movie I am trying to play. Restarting PMS sometimes works ok or I need to restart the whole system. I think 5% of the time it works fine but it getting rather frustrating now!!
This is the only main issues I am having with Plex, otherwise I am pleased.
