Cannot paste it inline because it is too big. I am attaching the logs
plex-debug.log (98.4 KB)

The issue started about a week back. I had updated the server around that time but the timeline is a bit fuzzy for me. The log [Transcode] [FFMPEG] - libva: /mnt/HD/HD_a2/Nas_Prog/plexmediaserver/binaries/lib/dri/iHD_drv_video.so init failed seems significant but other than a bug being introduced in that driver for Intel HD (which powers my WD PR4100), I can’t think of any reason why this would be corrupt. Reinstalling the application did not fix it.

Can a contributor to the source see if there were any changes around this driver? (If I can access the source myself and trace this, please let me know, I’ll be glad to help!)

Update 1: The logs didn’t resemble the certificate issue some users had. I refreshed the certificates anyway and as expected, it did not help.

An error occurred while attempting to play this video. Please check your connection and try again

I believe if you move that file somewhere else, Plex will download a new one. Give it a try

Found that I can send client side logs to the server too. Here are the server + client side logs.

Reminder, this works on the browser, chromecast and android.

Thanks for your response. I just tried it out. The driver file does not get regenerated. :frowning:
