Plex server is the newest release, running from Ubuntu (remotely). Xbox, iphone, Kodi connect/link without issue.
I created an account and linked my Roku to my account without issue. I, however, ran into an issue setting up my server (wasn't finding the media server), so I deleted my account. Created a new account (using a different email) and was able to successfully setup/link the server to my Plex interface.
Now the problem, when I try to input my 4 digit/letter code into plex.tv/link, I get "Your account has been successfully linked, please revisit your app to continue" -- yay, but on the TV I get: "Your credtentials have expired. Please sign in again."
I have three rokus and all have the same exact problem. Oddly, my authorized access list has the rokus listed.
I have deleted Plex from all three tvs. Reset the network connection. Restarted the rokus to no avail. :(
