I'm using LibreElec with TVHeadend as a dedicatd PVR. Did a fresh install of v9.3.2, using Realtek RTL2832 USB tuner for DVB-T and a Hauppauge Win-Nova-T for DVB-S. Initially it worked ok but after a couple of days I got the message shown in the Subject line when selecting TV or Guide.
I have searched without success for a solution.
The kodi.log showed some errors suggesting DNS problems. Switching from DHCP to manual network settings resolved these but not the problem of no response from the TVHeadend server (see below). I have no other add-ons installed except for Backup. Deleting TV*.db and Epg*.db from Userdata/Database didn't resolve. TVHeadend appears to be running ok. I can log in via the web UI and the EPG is displayed.
