http://localhost:8000/broadcasting/auth 404 (Not Found)

Look in config/app.php if you have uncommented

App\Providers\BroadcastServiceProvider::class,

There are two Service Providers with Same name but different namespace in config/app.php

Illuminate\Broadcasting\BroadcastServiceProvider::class, App\Providers\BroadcastServiceProvider::class, 

So uncomment both of them. It will work.

Hope your base url is wrong try to hardcore your base url like below

window.Echo = new Echo({ authEndpoint : 'http://*******/public/broadcasting/auth', broadcaster: 'pusher', key: '********', cluster: '***', encrypted: true }); 

Complete These Steps

1) In config/app.php uncomment this line-

App\Providers\BroadcastServiceProvider::class, 

2) If above not work and still you've got the error - then I'm sure you are not logged in. Just login to your account and check(because it's your private broadcast).

It'll solve your issue and since you can also pass additional auth parameters as your need in app\Providers\BroadcastServiceProvider.php

Broadcast::routes(['middleware' => 'auth:admin']); 

Laravel 11:

check bootstrap/app.php. It should contain channels param with correct path to the file:

return Application::configure(basePath: dirname(__DIR__)) ->withRouting( web: __DIR__.'/../routes/web.php', api: __DIR__.'/../routes/api.php', commands: __DIR__.'/../routes/console.php', //this line: channels: __DIR__.'/../routes/channels.php', health: '/up', ) 

UnComment this line in config/app.php :

App\Providers\BroadcastServiceProvider::class, 

and sure cache is clear with :

php artisan config:cache 

Done...

Are you missing csrf_token() in your blade file?

You can add in the meta tag

<meta name="csrf-token" content="{{ csrf_token() }}"> 

Check out your BroadcastServiceProvider.php and you should include your channel routes in the boot method.
