PVR Manager is starting up: 0% (stuck)

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.

The PVR client settings are at default values: 127.0.0.1, 9981, 9982, no username or password

Suggestions?

Yes, I can see the tuners at IP:9981 and they're working ok. The TVH server and client are on the same box. The server is set up with 3 usernames, admin, me, and *, with passwords for the first two, for administration, EPG browsing, and client interaction respectively. The 3rd is a default entry the first two are wizard created on first logging in to the web UI.

The client needs the IP of the server and 127.0.0.1 worked previously and I don't think hardcoding it to a 192.168.1.x will resolve (I've never known a machine not know where 127.0.0.1 is).

Update:

OK. Problem solved. Somewhere the default user * was deleted, perhaps when I added a user (myself) and I hadn't entered the username and password in the client.
