Accessing Qlik Sense Server using header authentication fails to exception

I try to connect the server with static header authenctication in .NET SDK:

  Qlik.Engine.ILocation loc = Qlik.Engine.Location.FromUri(new Uri(""));

        loc.VirtualProxyPath = "testi1";

        loc.AsStaticHeaderUserViaProxy("ValidUser", "HeaderAuthencticationHeaderName");


         using (IHub hun = loc.Hub())


            textBox.Text = hun.OSVersion();


This fails with the exception:


An unhandled exception of type 'System.Security.Authentication.AuthenticationException' occurred in Qlik.Engine.dll

Additional information: The remote certificate is invalid according to the validation procedure.


How to pass the validation procedure??
