I've been tied up with other things for weeks and am now just getting back
to trying to solve this problem.  Here are the last few lines of the log
from trying to launch mythwelcome from the command line in an xterm window:
2019-09-27 15:35:52.557130 I  MythCoreContext: Connecting to backend
server: 192.168.1.149:6543 (try 2 of 5)
2019-09-27 15:35:52.557635 E  MythSocket(14c5ca0:-1): Failed to connect to (
127.0.0.1:6543) Connection refused
2019-09-27 15:36:52.640164 I  MythCoreContext: Connecting to backend

2019-09-27 15:36:52.640674 E  MythSocket(14c5ca0:-1): Failed to connect to (
127.0.0.1:6543) Connection refused
ICE default IO error handler doing an exit(), pid = 4664, errno = 32
QWaitCondition: cv destroy failure: Device or resource busy
QWaitCondition: mutex destroy failure: Device or resource busy

It seems weird to me that it keeps switching between the correct IP address
(192.168.1.149) and the local loopback address (127.0.0.1).

Any suggestions on how to troubleshoot this?  I have no idea how to figure
out why the frontend/mythwelcome suddenly stopped being able to connect to
the backend.
