  password: 'gU******S',
});
client.on('connect', () => {
  console.log('hello');
  client.subscribe('v');
  client.publish('v', 'chal pa');
});
client.on('message', (topic, message) => {
  if (topic === 'v') {
    console.log('here my topic is v');
    // var connected = (message.toString() === 'true');
  }
  console.log('recived message from mqtt');
  console.log(message);
});

You have explicitly told the MQTTjs library to use native MQTT rather than MQTT over Websockets by using mqtt:// on the start of the URI.

If you want to use MQTT over websockets the URI should start with ws://

Secondly you are using port 1883, this is normally used for native MQTT not MQTT over websockets. The cloudmqtt docs suggest you should be using a port number that starts with a 3 to access the websockets listener.
