MQTT unable to connect over TLS

Question

I'm trying to connect to a MQTT broker over TLS in react-native with MQTT.js . Based on the doc I tried this code:

const options = {
  port: PORT,
  host: HOST,
  protocol: 'mqtts',
  secureProtocol: 'TLS_method',
  username: USERNAME,
  password: PASSWORD,
  ca: CA_FILE
}

const client = mqtt.connect(options);

client.on('error', (error) => {
  console.log("error", error);
});

client.on('connect', () => {
  console.log("connected");
});

The options object will be passed through tls.connect() , so I specified the certificate file.

The connection doesn't return an error, but the client is not connected. What did I do wrong?

Try to use that fork of React native MQTT https://github.com/FrozenPyrozen/rn-native-mqtt it worked with TLS connection on Android and IOS
