Plex no longer HW transcodes

[Sopranos]

After the upgrade from 6.11.5 to 6.12.X (on 6.12.10 now) everything worked just fine including the Plex, mind you I never tried to convert the quality, always played the original quality and it worked no problem.

I just tried to downgrade the quality of a movie, and it stops playing. after a min or two it throws an error msg on the client side - plex unknown error occurred 4294967279

 

All this time the Plex server is reporting all is well and it's transcoding yet it's not playing on the client side:

 

 

 

Transcoding is enabled of course. Nothing really changed other than the upgrade. The settings inside the Plex container stayed the same, I do have:

 

/dev/dri 

 

I am using linuxserver template, have been since day1 and it worked flawless. 

CoffeeLake-S GT2 [UHD Graphics 630]

 

 

Not sure how to proceed here? I tried restarting Unraid server. Restarted the docker still no luck. It just doesn't seem to be playing anything if I change the video quality to anything other then the original. Weird issue or what? 

 

Any help is much appreciated.

 

 

BTW there are some errors in the Plex Log file:
