Hello,
simple problem: I can connect to an HTTPS webservice using
.NET Windows Forms, but from my Pocket PC device using the .NET Compact
Framework I get the error from the subject:
"Could not establish secure channel for SSL/TLS".
I suspect it has something to do with authentication to our proxy server... ,
but using the exact same code from my desktop works fine
Here is the code snippet:
// connect to the webservice
private void btnConnect_Click(object sender, System.EventArgs e)
{
try
{
// connect to the webservice -> create webservice object
_ws = new SDiasPDA();
// trust all certificates -> always returns true
ServicePointManager.CertificatePolicy = new TrustAllCertificatePolicy();
// proxy authentication
WebProxy myProxy = new WebProxy("myproxy", 8080);
myProxy.Credentials = new NetworkCredential("login", "password", "mydomain.be");
_ws.Proxy = myProxy;
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
private void btnGetConnString_Click(object sender, System.EventArgs e)
{
try
{
// test() is a simple webservice method that returns a message
// HERE I GET THE EXCEPTION : Could not establish secure channel for SSL/TLS
MessageBox.Show(_ws.test());
}
catch (Exception ex)
{
ShowException("button1_Click", ex);
}
}
Can anybody give me some hint, please
There MUST be a solution for this problem...
Thanks in advance,

Can you capture the packet trace of the transfer using Ethereal, NetMon or with NETCF 2.0's logging functionality and send it to me This way we can analyze the trace. Also, the scenario is as follows, is it correct
Proxy authentication: Digest
Website authentication: SSL, no further authentication
What is the proxy used here How about the web server What is the signer of the web server's x509 certificate
Thanks,

Can you try using NETCF 2.0 to see if the application will work fine on it There are many authentication and SSL issues that are fixed on CF 2.0.

Are you using NETCF V2 or V1 What is the build number of the NETCF What is the authentication (Basic, Digest, NTLM, Negotiate) you are using
Thanks,

thanks for responding to my question.
I have already tried the exact same application on the .NET CF 2.0 and the same
error message is showing (on a Windows CE 5.0 emulator)..
The weird thing about this problem is that a .NET Windows forms application with exact
the same code does work fine. On my Pocket PC 2003 emulator, I can browse to the ASP Test Page of my webservice (I have to click yes one time in order to accept the certificate).
More ideas on the cause of this problem are more then welcome!
Thank you,

I am using .NET CF Vv1.0.5000 SDK.
Authentication is Digest.
Thanks for your answer,
