Pusher is not working on Production server- Laravel Broadcasting

Hi i am trying to up and running pusher on production server but it is only logging events to logs.

here are my settings for this

PUSHER_APP_ID=myappid
PUSHER_APP_KEY=myappkey
PUSHER_APP_SECRET=myappsecret

here is broadcasting.php

  'default' => 'pusher',


'connections' => [

    'pusher' => [
        'driver' => 'pusher',
        'key' => env('PUSHER_APP_KEY'),
        'secret' => env('PUSHER_APP_SECRET'),
        'app_id' => env('PUSHER_APP_ID'),
        'options' => [
            'cluster' =>'eu'
        ],
    ],

Broadcast service provider is also uncommented

App\Providers\BroadcastServiceProvider::class,

but it is still logging events to log i dont know why is there a solution. it is working fine on local
