Stephen:

I did the Application Autostart method before I started this thread and
that's where I was getting a hit or miss of the frontend being able to
connect..

Bill:

Your version of the systemd file worked, well, the first time The
"Attempting to connect" came up briefly, the progress bar got about a third
of the way across and then the menu screem.

Waited a few minutes and rebooted to see if it would start again. This time
the progress bar went all the way across and failed.
