There being "no information" is part of the bug report. That's all the log
says. The logger can do better.

Secondly, these networking errors can be detected, and when they happen, the
test script can "sleep" for a minute or two and then retry it. If it continues
to fail after N times, then the script can give up and quit.

After all, if the user can re-start the script, so can the script. The script
ought to be able to distinguish between an environmental error and a failure of
whatever is being tested.
