4-digit code not generated to connect Plex app on Samsung Blu-Ray to Plex server. Worked previously

I’ve been using the Plex app on my Samsung Blu-Ray player model BD-H6500 for years here in Germany without issue. However, in recent days I’ve had trouble connecting to the Plex server. I opted to delete the app on my Blu-Ray player and then re-install it. When started, it comes up with the screen where the 4-digit code for linking to the Plex server should be shown, but no code is ever generated. I’ve tried several times. I’ve tested internet access from the Blu-Ray player and it’s working fine. I’ve logged out/in from the Plex server. I also deleted the old version of the Blu-Ray device from the Plex server, thinking that may be causing the issue. Nothing has worked.

How can I link the Plex version on my Blu-Ray back to my Plex server if the 4-digit code is never generated?

Thanks…Brett

That model was released in 2014, with the last firmware upgrade launched in 2016

As such, I suspect that it due to age simply doesn’t support newer encryption protocols used to communicate with plex.tv
