      Socket._client.keepAlivePeriod = 10;
      Socket._client.port = 443;
      Socket._client.logging(on: !true);

      Socket._client.useWebSocket = true;
      Socket._client.websocketProtocols = ['mqtt'];

      Socket._client.server = "mqtt.padipos.id";
      Socket._client.secure = true;
      Socket._client.pongCallback = () => print("pong");
      Socket._client.onConnected = () => print('conn: connected');
      Socket._client.onDisconnected = () => print('conn: disconected');

      MqttConnectMessage connectMessage = MqttConnectMessage()
          .withWillTopic("WillMsg")
          .withWillMessage("SocketConsume closed abnormally..!")
          .withWillQos(Socket._qos)
          .keepAliveFor(10)
          .withProtocolVersion(4)
          .withProtocolName('WSS')
          .withClientIdentifier("hanumaniswandi1@gmail.com")
          .authenticateAs(
              "eyJlbmMiOiJBMjU2Q0JDLUhTNTEyIiwiYWxnIjoiZGlyIn0..piuspqkRuGLjvUrxi_upVg.2tktQ70ZYVCc2Dim7AhkhY4ZW00vG-kmtmTP_wei2CZhfqFMMEVgBMYNitaxjKb9_NkXtB-S0vxpKtFL1_kU5b3DCAkeyguo9M4VTGjgWvU8_kXR_EVpZFSnnreEwwRmv-4m3NglKBMM2yeHfaAIfby6klEScq8gfxCeHDfabKTjarKo-S0vpoKjIg7s1zEX.uabEoi6jIMJgj5R4rHDr1YWRMlqdPOXGeF-wwlat5ms",
              password);

use mqtt_client: ^5.6.1

thank for your attention :)

Don't know what you mean by dev environment or prod environment, this sounds like a flutter problem, the client doesn't change its behavior depending on its environment, the error is being generated by the Dart runtime, not the client.

[cahyowhy]

seems this issue is happen when i use 443 port

[shamblett]

Could you post the full log fromthe client connect, to use wss your server name should start with wss:// as in wss://mqtt.padipos.id I think

[cahyowhy]

got failed host lookup

[shamblett]

Post the log without the wss scheme

[cahyowhy]

same

[cahyowhy]

this is request header from browser using mqtt js

[cahyowhy]

its solved with this

Socket._client =
          MqttClient('wss://mqtt.padipos.id', "hanumaniswandi1@gmail.com");
      Socket._client.keepAlivePeriod = 30;
      Socket._client.port = 443;
      Socket._client.logging(on: true);

      Socket._client.useWebSocket = true;
      Socket._client.websocketProtocols = ['mqtt'];

      Socket._client.pongCallback = () => print("pong");
      Socket._client.onConnected = () => print('conn: connected');
      Socket._client.onDisconnected = () => print('conn: disconected');

      MqttConnectMessage connectMessage = MqttConnectMessage()
          .withWillTopic("WillMsg")
          .withWillMessage("SocketConsume closed abnormally..!")
          .withWillQos(Socket._qos)
          .keepAliveFor(30)
          .withProtocolVersion(4)
          .withProtocolName('MQTT')
