DVR doesn't record

I have an HDHomeRun Extend. I’ve setup the DVR to record and was careful to never record more than 2 at a time. It records okay for about 4 or 5 days and then just STOPS recording. No warning, I check and realize there was no recording of the show that was supposed to record. I can still watch Live TV, but it just doesn’t record. Is there a way to see if a show IS ACTUALLY RECORDING? There are no lights telling me on the HDHomeRun.
Just frustrating because I can’t just “let it ride”, it just stops.
Anyone having the same issues, what did you do to fix it?

I’ve only tried one show, and it has only failed. I summarized the problems in https://forums.plex.tv/discussion/292073/dvr-does-not-work-web-ui-shows-it-recording-but-nothing-saved-to-library/p1?new=1

Maybe your error messages in logs are similar
