cutting out mid show

Good Live Signal with Mohu Leaf 30, HD HomeRun Extend, Plex Media Server on Mac OS 10.13 Supplemental Update on 5 Oct. But Live signal cuts out after a 5-10 mins and recordings are only 5-10 mins long for half hour shows and 15-30 mins for hour long shows.

Can’t watch Live TV after repeated failures. Plex Media Server shows DVR is playing multiple channels (as many as 6 even though HD HomeRun can only do 2). Restarting Plex Media Server allows to restart Live TV, but recordings continue to fail after 5/30 mins as described.

Unplugging/Replugging HD HomeRun has not fixed issue. Seems to be a software issue with the server. Any ideas for a fix?

Thanks.
