HttpWebResponse HttpWRes = null;
HttpWebRequest HttpWReq = null;

//http://<BESName>:<BESPort>/push?DESTINATTION=<PIN/EMAIL>&PORT=<PushPort>&REQUESTURI=/
// Build the URL to define our connection to the BES.
string httpURL = "https://" + BESName + "/push?DESTINATION=2B838E45&PORT=32721&REQUESTURI=/";
//make the connection
HttpWReq = (HttpWebRequest)WebRequest.Create(httpURL);
HttpWReq.Method = ("POST");
//add the headers nessecary for the push
HttpWReq.ContentType = "text/plain";
HttpWReq.ContentLength = bytes.Length;
// ******* Test this *******
HttpWReq.Headers.Add("X-Rim-Push-Id", "2B838E45" + "~" + DateTime.Now); //"~" +pushedMessage +
HttpWReq.Headers.Add("X-Rim-Push-Reliability", "application-preferred");
HttpWReq.Headers.Add("X-Rim-Push-NotifyURL", ("http://" + BESName + "2B838E45~Hello~" + DateTime.Now).Replace(" ", ""));

HttpWReq.Credentials = new NetworkCredential("Username", "Password");
requestStream = HttpWReq.GetRequestStream();
//Write the data from the source
requestStream.Write(bytes, 0, bytes.Length);
//get the response
HttpWRes = (HttpWebResponse)HttpWReq.GetResponse();
var pushStatus = HttpWRes.Headers["X-RIM-Push-Status"];
//if the MDS received the push parameters correctly it will either respond with okay or accepted
if (HttpWRes.StatusCode == HttpStatusCode.OK || HttpWRes.StatusCode == HttpStatusCode.Accepted)

success = true;
}
else

success = false;
}
//Close the streams
HttpWRes.Close();
requestStream.Close();

I got the same error when I tried your code above. Replace
String BESName = "cp****.pushapi.eval.blackberry.com";
With
String BESName = "cpxxx.pushapi.eval.blackberry.com/mss/PD_pushRequest";
and make sure you provide the right username and password here:
HttpWReq.Credentials = new NetworkCredential("username", "password");
I got success = true;
However, even though the above code executed successfully, I still do not see the push message on the BlackBerry device.
