Laravel broadcast doesnt get triggered - laravel-5

Question

Trying to send user list to specific users after a friend requests been made.using pusher,vuejs 2.6,laravel 5.7 but in my function the broadcast its not getting triggered
when i do dd in channel it works! also in the construct function. so im kind of confused whether the broadcast itself gets called but I dont see a second XHR request for the list or some other situation !!?
//Boostrap.js
import Echo from 'laravel-echo'
window.Pusher = require('pusher-js');
window.Echo = new Echo({
broadcaster: 'pusher',
app_id: '7xxxx4',
key: 'xxxxxxxxxxxxxxxxxxx',
secret: 'xxxxxxxxxxxxxxxxxxx',
encrypted: false
});
//Vuejs component
mounted(){ window.Echo.channel("newReq").listen(".newreq-list", e => {
this.getrequestedList();
});
.env
BROADCAST_DRIVER=pusher
PUSHER_APP_ID=7xxxxx4
PUSHER_APP_KEY=xxxxxxxxxxxxxxxxxxx
PUSHER_APP_SECRET=xxxxxxxxxxxxxxxxxxx
PUSHER_APP_CLUSTER=ap2
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,
],
],
channels.php
Broadcast::channel('newReq', function(){
return true;
});
<?php
namespace App\Events;
use Illuminate\Broadcasting\Channel;
use Illuminate\Queue\SerializesModels;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Contracts\Broadcasting\ShouldBroadcastNow;
class Friendreq implements ShouldBroadcastNow
{
use Dispatchable, InteractsWithSockets, SerializesModels;
/**
* Create a new event instance.
*
* #return void
*/
public $req;
public function __construct($req)
{
$this->req = $req;
}
/**
* Get the channels the event should broadcast on.
*
* #return \Illuminate\Broadcasting\Channel|array
*/
public function broadcastOn()
{
return new Channel('newReq');
}
public function broadcastAs()
{
return 'newreq-list';
}
}
//in friendscontroller.php
broadcast(new \App\Events\Friendreq($requestToadd));
I have also uncommented App\Providers\BroadcastServiceProvider
for the result it should call the function this.getrequestedList(); which is a working function cause its also called in created()
Thanks for any help

2 days of debugging,searching was very simple :
PUSHER_APP_CLUSTER=ap2
the above line has to be CHANGED to this
PUSHER_APP_CLUSTER=eu
and now it gets triggered and working the way i want
