WebSocket connection to 'ws:https://localhost:1883/' failed:

[JamesArthurHolland]

I don't know why this is failing with the error:

WebSocket connection to 'ws:https://localhost:1883/' failed:

const protocol = "mqtt"
const host = "localhost"
const port = 1883

app.use(mqttVueHook, `${protocol}:https://${host}:${port}`, {
    clean: false,
    keepalive: 60,
    clientId: `mqtt_client_${Math.random().toString(16).substring(2, 10)}`,
    connectTimeout: 4000,
})

I can connect with the gui program MQTTLens no problem and subscribe to topics.

I've tried multiple different protocols, non seem to work. It shows as ws though even when I put mqtt or tcp.

The error reporting isn't really helpful. Is that from your lib or the underlying one?

Hi @JamesArthurHolland ,

Do you run your code in the browser? If yes, port 1883(mqtt:https://) is the default for native MQTT, not MQTT over websockets. Thus, your MQTT broker needs to listen websocket port(ws:https://) and be connected by it in the browser.
