Could not establish trust relationship for the SSL/TLS secure channel with authority

Hi,

i got a Console application and added a service reference for 1 HTTPS web service. below is my code to call the web service method:

 
using (clsSoapPortClient client = new clsSoapPortClient())
                {
                    client.Charge("user","pass",100);
                    client.Close();
                }

Open in new window


when the code reach the client.charge(); method i hit the error "Could not establish trust relationship for the SSL/TLS secure channel with authority".
