In my local machine broadcasting and it works fine but in Production which is Digital ocean app platform it cannot connect to the server.

in my controller i try to broadcast this

                       broadcast(new FileUploaded($user->id, $file->getClientOriginalName(), $counter, $asset->id));
                   } catch (\Exception $e) {
                       // Log detailed error information
                       Log::error('Error broadcasting FileUploaded event:', [
                           'message' => $e->getMessage(),
                           'file' => $e->getFile(),
                           'line' => $e->getLine(),
                           'trace' => $e->getTraceAsString(),
                       ]);
                   } 

i got following error:

Local. ERROR: Error broadcasting FileUploaded event: ("message": "Pusher error: CURL error 7: Failed to connect to 0.0.0.0 port 6001 after 6 ms: Connection refused (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://0.0.0.0/apps/my-app-id/events?auth_key=my-app-key&auth_timestamp=1727691940&auth_version=1.0&body_md5=bdfd3fdcc3c19ab647114c8d4ca230e2&auth_signature=cd729c19fa4d846b99f424b7a856584445272f695ffe9ff26cc786@fe0e39a71.", "file": "/workspace/vendor/laravel/framework/src/Illuminate/Broadcasting/Broadcasters/PusherBroadcaster.php", "line": 164, "trace": "#0 /workspace/vendor/laravel/framework/src/Illuminate/Broadcasting/BroadcastEvent.php(92): Illuminate\Broadcasting\Broadcasters\PusherBroadcaster->broadcast()")

Same thing happens with port 443 and port 8080 i got ssl error which is understandable. In console when i run start the server it is starting.

php artisan reverb:start --debug

   INFO  Starting server on 0.0.0.1:6001.  

  Pruning Stale Connections .......................................................................................

From postman i tried wss connection but it is tied out. I am out of options now.
