Got it.

Working on that "as we speak".

Looks like a timeout.  Here are the last trace entries:

Seventeen minutes after the last trace entry above is when I cancelled the job. 
 Debug data from the server end shows session "hangs" at presentation of server 
certificate.  I'm now waiting for our network folks to "poke a hole" in our 
firewall(s) so we can proceed to the next hurdle.
