Hello there!
I use my Macbook Air 2013 as Plex Server.
Pretty often when i start up my apple tv and click on trailers it just says connecting to trailers... (when my laptop is on)
Also when this problem occur, I can't connect to Apples Movies, it says the same thing.
So when it does i always go in to the network on the apple tv3 and put dns on automatic then back to 10.0.0.2 as usual, and it works.
Does anyone else got this problem?
