Can't Tune Channels - "No channel tuning parameter in request params"

Anyone have any idea how to troubleshoot this? I’m able to scan for channels fine in Plex just fine. I can even pull EPG data and match it to the channels without an issue. However, I’ve tried to tune to the channel in both the web app and my Roku, and it fails on both. No audio or video. Found this in the logs:

Not sure what this means or how to fix it. I’m using the latest Plex beta, 1.11.1.4768. My tuner is a WinTV-dualHD that I’m able to tune just fine in NextPVR and Kodi. Anyone have ideas?````````
