Connected connection was closed: Could not establish trust relationship for SSL / TLS secure channel
I have a web service that makes a soap request. When debugging in VS.NET 2008, the soap request completed successfully. However, when I deploy it, I get the following error:
The connected connection was closed: Could not establish trust relationship for the SSL / TLS secure channel.
There must be some security setting that I need to change, but I don't know what?
I tried to expand the code with:
System.Security.Cryptography.X509Certificates.X509Certificate cert = null; cert = new System.Security.Cryptography.X509Certificates.X509Certificate (); cert.Import ("C: \ customerCertFile.cer"); objRequest.ClientCertificates.Add (cert);
// WebProxy iBproxy = new WebProxy ("196.2.124.252", true); WebProxy iBproxy = new WebProxy ("192.1.1.1", true); iBproxy.Credentials = new NetworkCredential ("username", "password"); objRequest.Proxy = iBproxy;
Bad luck.
Thanks in advance!
