UN55C8000 can't login to server after user signed in
I have a samsung UN55C8000 manufactured in 2010 Plex App 1.019. I can access the PMS on my network with my master user id. If I try to use another user sign in using the code entered into their plex.tv/link I can sign in but can't reach the PMS. I'm able to login as another user on a newer Samsung TV.
