NotFoundHttpException dans RouteCollection.php dans Laravel

Fichier de Route

Route::get('/home', 'HomeController@index')->name('home');

Route::get('/' , ['as' => '/', 'uses' => 'LoginController@getlogin']);
 Route::post('/Login', ['as'=> 'Login' , 'uses' => 'LoginController@postLogin' ]);
 Route::get('/login', array('as' => 'login', 'uses' => 'LoginController@getLogin'));

 Route::group(['middleware'=>['authen','roles' ]], function(){   
    Route::get('/logout' , ['as' => 'logout' , 'uses'=> 'LoginController@getLogout']);
    Route::get('/dashboard',['as'=> 'dashboard', 'uses'=> 'DashboardController@dashboard']);
});

loginController

    class LoginController extends Controller{
        use AuthenticatesUsers;
        protected $username = 'username';
        protected $redirectTo = '/dashboard';
        protected $guard = 'web';

        public function getLogin()
        {`enter code here`
          if (Auth::guard('web')->check()){
            return redirect()->route('dashboard');
          }
            return view('login');
          }
         public function postLogin(Request $request)
        {
           $auth = Auth::guard('web')->attempt(['username'=>$request->username, 'password'=>$request->passwod , 'active' => 1]);

           if ($auth) {
             return redirect()->route('dashboard');
              }
            return redirect()-> route('/');
              }
         public function getLogout()
         {
            Auth::guard('web')->logout();
            return redirect()->route('/');
         }
    }

Chaque fois que j'essaie de connexion puis l'url va à "http://localhost:8000/login
" et NotFoundHttpException dans RouteCollection.php ligne 179: erreur de se produire.

J'ai essayé beaucoup de temps, mais je ne peux pas me connecter dans Laravel.
