Hello experts,
I am developing a client server application using SSL in vb.net. I followed the example here: http://msdn.microsoft.com/en-us/library/system.net.security.sslstream(v=vs.80).aspx to get it setup. I created a certificate file by extracting it from the .jks filw i created using java keytool, so it is self-signed. In my work, i used Mozilla Firefox browser as the client and my app is acting as the server. Whenever i load a page with "https://" prefix in mozilla firefox, it connects to my app and my app will show an unhandled exception saying: "The handshake failed due to an unexpected packet
format." on the line

"sStream.AuthenticateAsServer(cert, False, SslProtocols.Tls, True)"

I am totally confused. I dont know what to do again.
Here is my code:

'.....importing the necessary namespaces
Dim s As TcpListener = New TcpListener(IPAddress.Any, 8081)
s.Start()
Dim cert As X509Certificate = X509Certificate.CreateFromCertFile("mycert.cer")
Dim cs As TcpClient = s.AcceptTcpClient()
Dim sStream As New sslStream(cs.GetStream(), False)
 
sStream.AuthenticateAsServer(cert, False, SslProtocols.Tls, True)'this is where i got the error
 
'read message from client.......
'the rest of the code goes here

Pls help me
