I have read several posts on this subject with no joy. This is the second time this has happened to me. The first time I gave up after trying everything possible and blew the system away and started again. I am not keen on doing that again. One day I can access the menu and my Samsung TVs happily connect, then suddenly for no apparent reason, The TVs report no servers available and I cant get to the Server menu to rectify it. Access from a browser works but I need access from the TVs.
I am running Plex version 0.9.15.0.1621-344f193 on Ubuntu 14.04
Any help appreciated.
