I have the same issue here in our holiday apartment where we use Plex to access our tv channels and recordings from home. Things started to get bad at about one hour ago. Before, we have watched a recording for about an hour without any issues.
Same server and player version like @idf:
Server: 1.20.1.3252
Player: 3.13.21 (Plex for Smart TVs)
Edit: Access works from iOS App, Plex Windows App, both remote as well as “locally” via VPN
Looks to be some change that Panasonic have made to the app or on their servers as annoyingly all their apps seem to need to call home in some way, even though the content is local or not from them e.g. Netflix.
The same problem with two recently bought Panasonic TVs of 2020 year product line
(TX-55HXR940 and TX-43HXR900)
Both worked fine yesterday
Today both say that “device requires secure connection, but something went wrong, please check that Secure Connections server network setting is not set to Disabled”
Option is set to Preferred
Also tried Required - did not help
Tried re-login to server, unlink TV and link it again, manually specify Plex server’s IP, reinstall Plex App on TV and Plex Media Server on PC - nothing helped
Versions
Plex for Smart TVs: 3.13.21
Smart TV Alliance: 3.0
Plex Media Server: 1.20.1.3252-a78fef9a9 (Windows)
Happened to me as well. My TV isn’t even out of warranty. Using latest Plex. Tried downgrading to older Plex version but no good. Is there any way round this?
Plex App on my TV is missing some options including Fallback to Insecure Connections. Also it seems in your case Plex App in running in a kind of Dev mode. Can it be the cause of difference?
I have the same problem. Have tried everything Hefford has but no joy.
I am in the UK and my TV is the Viera TX GX800b, I believe it is a 2019 model so not old. Bought less than 6months ago from John Lewis.
Plex app version on the TV is 3.13.21.
Can not see a way to update the app on the TV’s app market.
Latest release running on the server and all other devices are working fine.
Have also just read that Plex stopped support for older smart TVs 30/09/2020.
If that’s the case mine is not an older TV and I wouldn’t expect it to stop working just like that.
That app version 3.13 is very old but not sure why you are not seeing the option to use “allow fall back to insecure”. Panasonics OS just can’t run the new versions of app thats why you don’t see the updates in their store.
I’m trying to find out of those models only support TLS 1.0 which is one of the main reasons those old devices are no longer supported
