Fires when server requires client certificate.

Private Sub object_ClientCertRequired()

The ClientCertRequired Event syntax has these parts:

This event is fired when remote server requires client certificate to be provided for SSL/TLS connection. It is possible that your authentication (and connection) still is successful - but it's also possible that server close the connection due to this requirement.

Of course, it will fire only if you did NOT provide your certificate in the first place.
