Unable to tune channel (no parts/no activity/timed out) error for NBC

For some reason my local NBC channel stops working in Plex and I get the above message while other channels seem to work fine. After a reboot of the server, it works again for a short time. I’m running the latest version of Plex server for QNAP NAS (Version 1.9.0.4252) and my HDHomeRun Connect has the latest firmware. Any tips or tricks or should I just wait for further updates/development? Otherwise, enjoying Live TV and DVR so far!

I have this same issue, channels are random on what cant be tuned. Reboot fixes for a little while.
