Hi,

I have a connection problem whit client M2Mqtt. I try to connect to my iot things in this way:


But message of Connax not arrive.
The strange is that a pyton script setting whit the same field, connect correctly, and the same for awsIotClient
Can you help me please
Thank's a lot

What I have tried:

C#
var caCert = X509Certificate.CreateFromCertFile(@"C:\DiscoD\MqttRuleDefault\root.crt");


var clientCert = new X509Certificate2(@"C:\DiscoD\MqttRuleDefault\xxxx-certificate.crt");

           
string path = @"C:\DiscoD\MqttRuleDefault\xxxxx-private.pem.key";
string privateKey = this.GetStringFromFile(path);
byte[] keyBuffer = Helpers.GetBytesFromPEM(privateKey, PemStringType.RsaPrivateKey);


RSACryptoServiceProvider prov = Crypto.DecodeRsaPrivateKey(keyBuffer);
clientCert.PrivateKey = prov;

Console.WriteLine(clientCert.HasPrivateKey);

Console.WriteLine(clientCert.Issuer);
Console.WriteLine(clientCert.Verify());

RemoteCertificateValidationCallback cb = new RemoteCertificateValidationCallback(Pippo);
LocalCertificateSelectionCallback lcb = new LocalCertificateSelectionCallback(Pippo1);

var client = new MqttClient("yyyyy-ats.iot.us-west-2.amazonaws.com", 443, true, caCert, clientCert, MqttSslProtocols.TLSv1_2, cb, lcb, new List<string>() { "x-amzn-mqtt-ca" });

         
string clientId = Guid.NewGuid().ToString();


client.ConnectionClosed += Client_ConnectionClosed;
client.MqttMsgPublished += Client_MqttMsgPublished;
client.MqttMsgPublishReceived += Client_MqttMsgPublishReceived;
client.MqttMsgSubscribed += Client_MqttMsgSubscribed;
client.MqttMsgUnsubscribed += Client_MqttMsgUnsubscribed;


client.Connect(clientId);

IThink to be solved, connect to 8883 port with client certificate exported to pfx with private key
