laravel websocket "Failed to connect to 127.0.0.1 port 6001" on docker

Hi, I'm building an app that must have a real time chat and i don't want to use the pusher api. I'm using docker-compose as dev enviroment :

version: '3.9'

services:
  #php
  php:
    build: 
      context: .
      target: php

I'm following a tutorial on how to use laravel webserver or soketi as pusher alternative

broadcasting.php:

        'pusher' => [
            'driver' => 'pusher',
            'key' => env('PUSHER_APP_KEY'),
            'secret' => env('PUSHER_APP_SECRET'),
            'app_id' => env('PUSHER_APP_ID'),
            'options' => [
                'cluster' => env('PUSHER_APP_CLUSTER'),
                'encrypted' => false,
                'useTLS' => false,
                'host' => '127.0.0.1',
                'port' => 6001,
                'scheme' => 'http'
            ],

websockets.php:

    'apps' => [
        [
            'id' => env('PUSHER_APP_ID'),
            'name' => env('APP_NAME'),
            'key' => env('PUSHER_APP_KEY'),
            'secret' => env('PUSHER_APP_SECRET'),
            'enable_client_messages' => false,
            'enable_statistics' => true,
        ],
    ],

bootsrap.js:

 window.Echo = new Echo({
    broadcaster: 'pusher',
    key: process.env.MIX_PUSHER_APP_KEY,
    wsHost: '127.0.0.1',
    wsPort: 6001,
    enabledTransports: ['ws', 'wss'],
    forceTLS:false,
    disableStats:false,
    encrypted: false,
    cluster:'eu',
});

The connection is ok, but when i try to send an event i get this error (i'm using the laravel-websocket debug page):

Pusher error: cURL error 7: Failed to connect to 127.0.0.1 port 6001: Connection refused (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for http://127.0.0.1:6001/apps/1567724/events?

what am i doing wrong?
