I ssh out to a different IP and scp it, using that exact line. It works.
It worked when I originally put it up because someone else copied it off then.
When it locks you out, you don't get any response, and you did get a transfer started.
[chucky@firewall ~]$ scp -P 443 webinar@<post-in-this-thread-for-ip-address>:OpenPilot*.mp4 .

This did copy some of the file. I had to erase the partial file.
