I am using the below code for push notification.
public void PushNotificationIOS(string message, string registrationKey)
{
string deviceID = registrationKey;
int port = 2195;
String hostname = System.Configuration.ConfigurationManager.AppSettings["HostName"];//"gateway.sandbox.push.apple.com";
string certPath = string.Empty;
certPath = System.Configuration.ConfigurationManager.AppSettings["CertificatePath"] + System.Configuration.ConfigurationManager.AppSettings["Cer
String certificatePath = System.Web.HttpContext.Current.Server.MapPath(certPath);
string certPassword = System.Configuration.ConfigurationManager.AppSettings["CertificatePassword"];
TcpClient client = new TcpClient(hostname, port);
try
{
X509Certificate2 clientCertificate = new X509Certificate2(System.IO.File.ReadAllBytes(certificatePath), certPassword);
X509Certificate2Collection certificatesCollection = new X509Certificate2Collection(clientCertificate);
SslStream sslStream = new SslStream(client.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null);
sslStream.AuthenticateAsClient(hostname, certificatesCollection, SslProtocols.Tls, false);
MemoryStream memoryStream = new MemoryStream();
BinaryWriter writer = new BinaryWriter(memoryStream);
writer.Write((byte)0);
writer.Write((byte)0);
writer.Write((byte)32);
writer.Write(StringToByteArray(deviceID.ToUpper()));
String payload = "{\"aps\":{\"alert\":\"" + message + "\",\"badge\":0,\"sound\":\"default\"}}";
writer.Write((byte)0);
writer.Write((byte)payload.Length);
byte[] b1 = System.Text.Encoding.UTF8.GetBytes(payload);
writer.Write(b1);
writer.Flush();
byte[] array = memoryStream.ToArray();
sslStream.Write(array);
sslStream.Flush();
client.Close();
}
catch (System.Security.Authentication.AuthenticationException ex)
{
client.Close();
}
}
I am getting the following error Authentication failed because the remote party has closed the transport stream. On Trace, I am getting the below
System.Net.Security.SslState.CheckThrow(Boolean authSucessCheck)
at System.Net.Security.SslState.get_SecureStream()
at System.Net.Security.SslStream.Write(Byte[] buffer)
I tried all the things mentioned in various post but am not able to solve the issue.
