GPU Transcoding not working

New Unraid server with Fresh Plex install. I had a spare gtx 1060 6GB card laying around so I put it in my new server to allow for 4K transcoding to my Roku devices that have older 1080p TVs attached.

I have the Nvidia driver app installed and I can see on the “Unraid Dashboard” that plex is accessing the GPU. My Roku player gets stuck at the initial 13% and won’t load the movie. It worked only once and never again. I turned on Verbose logging on Plex and started a movie “300” at about 2100 hours from the :“office” Roku player.
Any ideas? Not sure how to attach a log file.
