password has sessionid account login instagram password: 'sessionid=2548556%djljjjfafhhhnannf,a,,ga'

thats my code to connecting :

`Future connect(String server, int port, String clientIdentifier, String username, String password, {bool isSsl = false}) async { final client = MqttServerClient(server, clientIdentifier); //final client = MqttClient(server, clientIdentifier);

client.port = port;

client.secure = true;
final currDir = '${path.current}${path.separator}crt${path.separator}';
final context = SecurityContext.defaultContext;

//context.setTrustedCertificates(currDir + path.join('pem', 'roots.pem'));
client.securityContext = context;
//client.setProtocolV311();
client.setProtocolV31();
client.logging(on: true);
await client.connect(username, password);

}`

but gets this errors :

You seem to have connected successfully -

I/flutter ( 9842): 6-2021-04-24 15:22:04.081055 -- SynchronousMqttServerConnectionHandler::internalConnect - connection complete

The broker is rejecting your connect message because of a protocol failure, there are many reasons for this, try using a pared down connection message rather than the default -

final connMess = MqttConnectMessage()
      .withClientIdentifier('Android-125432102')
      .startClean() // Non persistent session for testing
      .authenticateAs(username, password)
  client.connectionMessage = connMess;
await client.connect(username, password);

You must send what your broker expects, also you need to use the MQTT version your broker requires, you should consult your broker specs for this. At the end of the day only your broker knows why its rejecting the connection, you should check your brokers logs.

Thanks for the reply The previous error remains

The broker is not responding to the connection request message (Missing Connection Acknowledgement?

OK the client is telling you this -

The broker is not responding to the connection request message (Missing Connection Acknowledgement?

The only way to find out exactly why is to examine your brokers logs.
