hi, I’m using the HiveMQ ‘Getting started’ code example using MQTT.JS over a web browser (Chrome) in a React app and I get this error.

**WebSocket connection to ‘wss://localhost:8883/’ failed:**

I also get the error when I use port: 8884 and I even get it when I use protocol **WS**.

my code looks like this:

```auto

import React, { useEffect } from 'react'

import * as mqtt from 'mqtt'

const ReactComponent = ()=> {
    var options = {
		host: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.s1.eu.hivemq.cloud',
		port: 8883,
		protocol: 'mqtts',
		username: 'myname',
		password: 'mypassword'
	}

	useEffect(() => {
		let client = mqtt.connect(options)
		client.on('connect', function() {
			console.log('Connected')
			// Subscribe to a topic
			client.subscribe('testing', function(err) {
				if (!err) {
					// Publish a message to a topic
					client.publish('testing', 'Hello mqtt')
				}
			})
		})
	}, [])

```

Does anyone know what could be happening wrong?
