Hi Carlos,

When you use TLS, the browser typically switches to port 443.  The WSDL
request (add web reference) goes over HTTP get, and I suspect is directed
in your case over port 80.

It would seem that you are routing through a proxy server that does not
support port 443 operations.  I think the only remedy would be to switch to
a router that does support secure sessions.  There may be an administrative
option that your IT department has set to prevent them from not being able
to monitor secure traffic.

I hope this helps

Hi !!!

I have a VB.Net application that consumes an WebService. The problem is
that
the HTTP address works fine, but it will change to an HTTPS address, and it
isn't working.

The weird thing is that I could add the WebReference and view the WSDL in
my
browser (even in my iPaq Internet Explorer) without any problem, when I try
to consume the WebService I get the following error message: "The
ServicePointManager does not support proxies of https scheme."

What causes this error? How can I fix it or workaround?
Why I can add the WebReference and cannot consume the WebService?

Thanks in advance,
