Samsung TV Connection Problem

[ataribaby]

I can get the versions and logs upon request but for now:

I saw the announcement which i presumably a result of the spate of certificate errors the internet is suffering from:

Important information about Plex for smart TVs after September 30, 2021

UPDATE: It appears that all Tizen-based Samsung sets are likely affected by the cert change and will thus need the app and server configured to allow insecure connections. On September 30, 2021, some older smart TVs (some Samsung, LG, Vizio, Hisense, and other unsupported TV platforms) will no longer be able to use secure connections to communicate with Plex Media Servers. These devices are no longer supported by their manufacturers, and won’t be receiving an update needed to continue making se…

Anyway, the server and TV were already set to that, but we still get the error. This just started within the last two weeks. Plus, this is a UN65RU7300FXZA, which I think is less than two years old, so not an “older” Samsung.

Anyone know what to do? Or is there a fix coming put? Everything seems fully updated. I did put in a new router, an Eero Pro 6, do I need to open any ports? The server is remote, outside the local network of the TV.
