Can't receive events broadcasted on Laravel - laravel

Question

I've been struggling for a while now and can't find a way to make this work.
My project is on Laravel 8
I'm using Redis and laravel-echo-server (since it doesn't seem maintained I also tried with a hand-made express/socket.io server)
The problem : When I fire the event, it's received by Redis and Laravel Echo Server but it's never received on my webpage's console.
"Events/SendMessage"
<?php
namespace App\Events;
use Illuminate\Broadcasting\Channel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;
class SendMessage implements ShouldBroadcast
{
use Dispatchable, InteractsWithSockets, SerializesModels;
/**
* Create a new event instance.
*
* #return void
*/
public function __construct()
{
//
}
/**
* Get the channels the event should broadcast on.
*
* #return \Illuminate\Broadcasting\Channel|array
*/
public function broadcastOn()
{
return new Channel('user-channel');
}
public function broadcastAs()
{
return 'UserEvent';
}
public function broadcastWith()
{
return [
'title' => 'This notification is awesome'
];
}
}

});

import Echo from 'laravel-echo';
window.io = require('socket.io-client');
window.Echo = new Echo({
broadcaster: 'socket.io',
host: window.location.hostname + ":6001"
});
Hope someone can help me
