使用auth中间件时未显示Laravel 5.2.X验证错误消息

Question

我正在开发一个项目，我被指派使用laravel开发Web应用程序。我正在使用laravel 5.2.x，当路由不在登录，注销等的auth组中时，每个工作正常。

登录后，我定义了一个只能由经过身份验证的用户访问的组，例如admin。

routes.php文件

/ Authentication Routes...
$this->get('/login', [ 'as' => 'auth.loginForm', 'uses' => 'Auth\AuthController@showLoginForm']);
$this->get('/', [ 'as' => 'auth.loginRoot', 'uses' => 'Auth\AuthController@showLoginForm']);
$this->post('/login',[ 'as' => 'auth.login', 'uses' => 'Auth\AuthController@login']);
$this->get('/logout', [ 'as' => 'auth.logout', 'uses' => 'Auth\AuthController@logout']);

// Password Reset Routes...
$this->get('/password/reset/{token?}', [ 'as' => 'auth.resetForm', 'uses' => 'Auth\PasswordController@showResetForm']);
$this->post('/password/email', [ 'as' => 'auth.passwdEmail', 'uses' => 'Auth\PasswordController@sendResetLinkEmail']);
$this->post('/password/reset', [ 'as' => 'auth.reset', 'uses' => 'Auth\PasswordController@reset']);

Route::group(['middleware' => ['auth']], function(){

....

$this->get('/register', [ 'as' => 'auth.register', 'uses' => 'Auth\AuthController@showRegistrationForm']);
    $this->post('/register', [ 'as' => 'auth.create', 'uses' => 'Auth\AuthController@register']);
    $this->get('/register/verify/{confirmationCode}', ['as' => 'auth.confirmation', 'uses' => 'Auth\AuthController@confirm']);
    $this->get('/dashboard', [ 'as' => 'auth.dashboard', 'uses' => 'Auth\AuthController@index']);

....
});

现在，当我在控制器上执行dd()时，注册页面上的验证工作正常，但错误消息未显示在刀片​​中。我在登录时做的验证，这些工作正常。我不明白实际问题是什么。

更新 会话闪存消息也不会显示，有时会显示，但大多数时候这些错误或会话闪存消息都不会显示。
