Broadcasting with Laravel Echo, laravel-echo-server and socket.io won't work

Question

I've setup websockets with Laravel sucessfully with an own implementation. Now I'd like to switch to Laravel Echo and laravel-echo-server. But, after many hours of trying and reading every piece of documentation I could find, I do need further help.

What's happening when I fire an event: The queue worker processes the event as desired: "Processed: Illuminate\Broadcasting\BroadcastEvent". But nothing happens in the laravel-echo-server console nor on the client.

Some information:

Laravel is running on port 8001
Redis is running on 6379
the queue worker is running (php artisan queue:work)
Laravel, Redis and laravel-echo-server are running on the same machine (192.168.134.214)
when trying private channels the authentication in the BroadcastServiceProvider seems to work (the server writes errors to the console if it fails)
the client uses the socket.io script of the laravel-echo-server: <script src="//192.168.134.214:6001/socket.io/socket.io.js"></script>

Excerpt of my .env:

BROADCAST_DRIVER=redis
CACHE_DRIVER=redis
SESSION_DRIVER=redis
QUEUE_DRIVER=redis

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

The laravel-echo-server.json:

{
    "appKey": "<myAppKey>",
    "authEndpoint": "/broadcasting/auth",
    "authHost": "http://localhost:8001",
    "database": "redis",
    "databaseConfig": {
        "redis": {
            "port": "6379",
            "host": "http://localhost"
        }
    },
    "devMode": true,
    "host": "192.168.134.214",
    "port": "6001",
    "sslCertPath": "",
    "sslKeyPath": ""
}

app.js

import Echo from "laravel-echo"

window.Echo = new Echo({
    broadcaster: 'socket.io',
    host: 'http://192.168.134.214:6001',
});

app.blade.php

<script>
    Echo.channel('mychan')
        .listen('myevent', (e) => {
            console.log('Hello World!', e);
        });
</script>

Parts of the Event "NewsPublished":

class NewsPublished implements ShouldBroadcast {
    use InteractsWithSockets, SerializesModels;

    public function broadcastOn() {
        return new Channel('mychan');
    }

    public function broadcastAs() {
        return 'myevent';
    }
}

..and I'm firing the Event with event(new App\Events\NewsPublished());

I was hoping to get some information out of the laravel-echo-server when switching "devMode" to true. But that doesn't seem to change anything!

I doubt if this is the issue, but php artisan queue:work doesn't start the process of the queue worker listening for jobs - it merely processes the next job on the queue then exits. I think you're looking for php artisan queue:listen. — swatkins

In your redis configuration, you've included http:// as a protocol with the host. You will need to remove the protocol and simply use localhost or 127.0.0.1

{
...
"databaseConfig": {
    "redis": {
        "port": "6379",
        "host": "localhost"
    }
...
}

*Aside: If you have the ability to use a socket, consider using "path": "/path/to/sockfile" in-place of "host"; that's moreso about performance but I'm sure this correction should get it working.

For reference, here's a redacted version of the laravel-echo-server.json configuration that I am using.

{
  "appKey": [omitted],
  "authEndpoint": "/broadcasting/auth",
  "authHost": "http://localhost",
  "database": "redis",
  "databaseConfig": {
    "redis": {
      "db": 2, /*this is an intentional change; the default is zero(0)*/
      "path": "/tmp/redis.sock",
      "password": [omitted]
    }
  },
  "devMode": false,
  "host": "",
  "port": "6001",
  "referrers": [
    {
      "host": "*", /*matches any referrer*/
      "apiKey": [omitted]
    }
  ],
  "sslCertPath": "",
  "sslKeyPath": "",
  "verifyAuthPath": true,
  "verifyAuthServer": false
}

Great! Running redis on a unix socket and configuring it in the laravel-echo-server has done the trick. Thank you very much!
