The Plex Tuner Server.log does not show successful discovery of the DVR on 192.168.43.101 with an error being returned when the device status is requested - i am guessing at the moment that dvb#hdhr#0'272386583 is actuall DVR with device if 103C4A17

A previous report of similar issue was reported back as was being a firewall issue - see HDHomerun not found
Could you look into the firewall rules
Also try the LineupURL for that DVR - the one you redacted. Try it in a browser and see what you get back
