When you try to open WSDL link in any browser, you see this warning message :

So. it's easy to override this screen accepting "Continue to this website". But in SOAP request, there is no notification screen like that. You couldn't accept it. Here is the solution for .NET, how to accept unauthorized certificate.

In your client code where SOAP request, before consuming web services, use this statement :

C# Solution
ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };


VB.NET Solution
Dim delCert = Function() Return True
ServicePointManager.ServerCertificateValidationCallback = delCert

Note: Don't forget to add following namespaces : 
System.Net
System.Net.Security
System.Security.Cryptography.X509Certificates

If you check the statement, anonymous method always returns true. This means, accept all certificate regardless of their authorization.
