just reeinstaled plexserver an after i cant connect thrue my lg tv anymore ( 50PM670T )
i can se the server when i seach for it but it wont connect.
did you sign in to your new plex install?
Maybe try and delete the App from LG and re-install so it will reconnect to new plex install?
not even geting to that point.
