[Mono-list] Security exception when I'm trying to connect to a google Account…

[LordPhoenix]

Hi all, 

I'm trying to connect to a google account but I'm getting security
exception.  
Here is my code : 
string url = String.Format
("http://www.google.com/accounts/ClientLogin?service=reader&Email={0}&Passwd={1}", _username, _password);
			HttpWebRequest wreq = (HttpWebRequest)WebRequest.Create (url);
			wreq.Method = "GET";
			HttpWebResponse response = (HttpWebResponse)wreq.GetResponse ();

And I get this message : 

System.Reflection.TargetInvocationException: Exception has been thrown
by the target of an invocation. ---> System.Net.WebException: Error
getting response stream (Trust failure): TrustFailure --->
System.IO.IOException: The authentication or decryption has failed. --->
Mono.Security.Protocol.Tls.TlsException: Invalid certificate received
from server.
  at
Mono.Security.Protocol.Tls.Handshake.Client.TlsServerCertificate.validateCertificates (Mono.Security.X509.X509CertificateCollection certificates) [0x00000]

How can I solve this? 

Thanks for help

PS Sorry for my bad English I don't speak it very often.
