Laravel WebSockets cannot send event - php

Question

I'm having troubles with dispatching events on my local Laravel configuration.
I'm trying to dispach it directly from the dashboard http://localhost:8000/laravel-websockets, but it always return Error sending event. Even if it is connecting to the dashboard.
My config looks:
.env file:
QUEUE_CONNECTION=database
QUEUE_DRIVER=sync
BROADCAST_DRIVER=pusher
PUSHER_APP_ID=local
PUSHER_APP_KEY=local
PUSHER_APP_SECRET=local
PUSHER_APP_CLUSTER=mt1
PUSHER_PORT=6001
PUSHER_SCHEME=http
PUSHER_HOST=127.0.0.1
Configuration in boradcasting.php:
'pusher' => [
'driver' => 'pusher',
'key' => env('PUSHER_APP_KEY'),
'secret' => env('PUSHER_APP_SECRET'),
'app_id' => env('PUSHER_APP_ID'),
'options' => [
'host' => env('PUSHER_HOST', 'api-'.env('PUSHER_APP_CLUSTER', 'mt1').'.pusher.com') ?: 'api-'.env('PUSHER_APP_CLUSTER', 'mt1').'.pusher.com',
'port' => env('PUSHER_PORT', 443),
'scheme' => env('PUSHER_SCHEME', 'https'),
'encrypted' => true,
'useTLS' => env('PUSHER_SCHEME', 'https') === 'https',
],
Configuration in websockets.php:
'apps' => [ [
'id' => env('PUSHER_APP_ID'),
'name' => env('APP_NAME'),
'key' => env('PUSHER_APP_KEY'),
'secret' => env('PUSHER_APP_SECRET'),
'path' => env('PUSHER_APP_PATH'),
'capacity' => null,
'enable_client_messages' => false,
'enable_statistics' => true,
],
],
I did enable all providers, and still not dispatching even from the dashboard.
I tried to create event and dispatch from the controller, but still not working.
Any ideas what could cause it?
Edit: just noticed in dashboard a message like:
Channels current state is connected
