I have seen similar post and no definitive solution.
Plex does not allow to be configured, when it is launched it automatically stays “Unable to connect to he plex website” with Retry , exit or home as its options it also has PIN window behind this window
In trying to configure the account one cannot enter a user name or password for the plex account and displays the “Login result” windows
When entering Manual configuration mode, it does not except the IP address of the local plex server.
I have uninstall the app and reinstalled,. nothing work.
The Tv has an IP address
The TV has internet access
Neflix and Hulu work just fine.
Plex account is active - and work on PC
Is there any solution to this? thank you in advance.
