title: Cannot consume webservice over ssl
body: <p>I am trying to consume webservice over https protocol. I have password-protected p12 file with certificate. After importing this file I can view service methods over browser and I can add service as a ServiceReference in VisualStudio client application. Problem appears while invoking methods of this service. I tried almost everything and still get error 'Could not establish secure channel for SSL/TLS with authority {server_name}'.
  What can be wrong?</p>
