Help Troubleshooting Recording Errors

Hello, brand new to Plex DVR, just purchased a HDHR Connect Quatro and set it up this weekend. I have my recording schedules setup, and I noticed at random recordings will fail with two different errors so far, “an error occurred while postprocessing the recording” and a more generic “there was a transcoder error”. I’m running Plex Server version 1.10.0.4523 on an Intel Skull Canyon NUC on Ubuntu 16.04.3. My recording are landing on a Synology DS1815+ cifs mounted to the NUC as /mnt/movies, /mnt/tv_shows, etc. All three devices are connected to the same switch.

I disabled comm skip to hopefully resolve the first error, but any pointers you can give me on how to start troubleshooting, I’d appreciate it. I also have “convert videos while recording” set to OFF.

Thanks!

Look in the Plex Media Server log file around the time of a failed recording for any messages.

Looking at logs for the transcoder error, I see this:

I assume this means the HDHR didn’t respond in time?
