framework: PusherBroadcaster exception "Failed to connect to Pusher" when running in queue

• Laravel Version: 5.3.23
• PHP Version: 5.6.15
• Database Driver & Version: MySql 5.6.31
• OS : Windows 8.1 64bits

Description:

I’m using the “broadcast” notification channel to notify the user via pusher.

When not using queue or using queue with the sync driver every thing works as expected, and i receive the notification. But when i use the database driver for queues, the app can’t connect to pusher. This is the log.

local.ERROR: exception 'Illuminate\Broadcasting\BroadcastException' with message 'Failed to connect to Pusher.' in F:\wamp3\www\opendata\vendor\laravel\framework\src\Illuminate\Broadcasting\Broadcasters\PusherBroadcaster.php:105

Edit: I’m also using the mail and database channels in the same notification. These two always work, even from the queue with database driver.
