Same Issue ALL of my TVs, LG TV running WEBOS 5.4.2, and my other two older Samsung TVs.
I can access the server using my IPAD & Roku, 90% of our PLEX viewing is done on my LG tv.
My last successful use on my LG tv was the 26th of Oct.
One other piece of the puzzle is that on Oct 29th I switched to a new ISP and started using an Arris modem as my DHCP Server instead of my older Technicolor modem, some networked items needed re-booted but all other networked items work fine after the Arris modem install.
I did follow the directions that PLEX sent out regarding “Important information about Plex for smart TVs after September 30, 2021”
While on the server computer (win 10) PLEX Version 1.24.4.5081, the “Authorized Devices” show all of the TVs had access a few minutes before I wrote this plea for help.
This could be a BIG issue as soon as my wife wants to use our 65" Samsung tv to watch PLEX content. Any HELP would be greatly appreciated!
Update: 11/1/21 => On my LG tv If I set the Plex setting “Manual Servers” connection 1 to the IP address of the windows computer that is running the Plex server it seems to correct the problem. My windows server is NOT a static IP and I would prefer not to make it a static address. I think this is just a band-aid for now until Plex figures something out…
Maybe it is a clue as to what changed?
