----------------------------------------------
[~elecharny] I enabled SSL debugging and compared between a successful & a
failed run and the only difference I found in the SSL debug output was the
below stuff
{code}

This is very interesting: {{Input SSL/TLS record too big: max = 33305 len =
50586}}
The stack trace in the log just shows
