From that server, can you get to the URL using IE (or any other web browser)?
Is the server's certificate valid?

The vendor had tightened up their SSL security on their firewall and so was dropping our connection from our web server as 2003 does not support the deployment of the most recent version of SSL and TLS. Put the routine on our new app server that runs 2008 and created a redirect to it.
Excellent! Thanks, and thanks again for the points.
