no media server found

I have been running plex through my lg w5700 media link for a long time and had no problems. yet in the last couple of days has been coming up media server not found.
if I click on device selection on tv it shows the plex media server on my and my wifes computers yet when select them still comes up no media server found.
I am running version 1.1.3.2700 of plex media server.
anyone have any ideas?

Yes. Clients have to be logged in to your account to access the server.
Your LG client does not support this.
You have to add the IP of your TV to the exception list in the server config.

k how can I do this? as can’t find server config
