Laravel 5 Artisan::call dose not work correctly

Question

I use Laravel 5.5 and I have Controller like this.

use Illuminate\Support\Facades\Artisan;
---------------------
public function index()
{
    Artisan::call('config:cache');
}

but it not work correctly and show me this message in browser:

The connection was reset.

Try:

It already worked but it not work correctly now.
