Не могу получить доступ к админ-панели Laravel

Я новичок в структуре Laravel. Я купил проект, и я установил его, но когда я пытаюсь войти в админку локальный / администратор / дома это перенаправляет меня на первую страницу. Почему это? Проблема в аутентификации?

Шаблон adminLTE.

Это маршруты. Php:

   <?php

/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.

Route::auth();
Route::get('/', function () {
// $user = Auth::user();
// if($user->id  == 2){
return view('welcome');
/* }else{
echo "Site En cours de mise a jours .. Veuillez patienter quelques minutes";
die();
}*/});
