Recently I also received error: "A call to SSPI failed. The message received was unexpected or badly formatted." with internal exception: "Authentication failed because the remote party has closed the transport stream"

What helped me is to change a little OpenSslStream method - TSL in SSL protocol

old code:

apnsStream.AuthenticateAsClient(
    this.Host, this.certificates, 
    System.Security.Authentication.SslProtocols.Ssl3, 
    false
);

new code:

apnsStream.AuthenticateAsClient(
    this.Host, this.certificates, 
    System.Security.Authentication.SslProtocols.Ssl3 | System.Security.Authentication.SslProtocols.Tls,
    false
);

Hopefully it will help someone...

Had the same issue. In my case only after applying both solutions X509Certificate -> X509Certificate2, X509CertificateCollection to X509Certificate2Collection and adding SslProtocols.Tls flag fixed the issue. So, both answers are correct and both are required to resolve the topic – Madman Nov 24 '14 at 14:07

you can try by changing X509Certificate to X509Certificate2 and X509CertificateCollection to X509Certificate2Collection.

I think problem here is you have convert certificate from apple to certificate on server developement, you could use following command in openssl to do that:

command1: openssl x509 -in "apn_developer_identity.cer" -inform DER -out "apn_developer_identity.pem" -outform PEM
command2: openssl pkcs12 -nocerts -in "pushkey1.p12" -out "pushkey1.pem" -passin pass:yourpass -passout pass:yourpass
command3: openssl pkcs12 -export -inkey "pushkey1.pem" -in "apn_developer_identity.pem" -out "apn_developer_identity.p12" -passin pass:yourpass -passout pass:yourpass

Try the below code sslStream.AuthenticateAsClient("gateway.sandbox.push.apple.com", clientCertificateCollection, SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls, false);

Try to create the certificate with Private key only.

Personally I use this :

sslStream.AuthenticateAsClient("gateway.sandbox.push.apple.com", clientCertificateCollection, SslProtocols.Default, false);

            using (TcpClient client = new TcpClient())
            {


                client.Connect("gateway.sandbox.push.apple.com", 2195);


                using (NetworkStream networkStream = client.GetStream())
                {
                    try
                    {

                        SslStream sslStream = new SslStream(client.GetStream(), false);


                        try
                        {
                            sslStream.AuthenticateAsClient("gateway.sandbox.push.apple.com", "gateway.sandbox.push.apple.com", SslProtocols.Default, false);
                          //building messages
                          sslStream.Write(msg);
                          sslStream.close();

Thanks malinois. I checked your line of code, but it returns the same error. Can u please post the code and steps to do for this APNS using C#. Thanks in advance. Your help is very much appreciated. — Kodee, Jan 11 '11 at 10:23
