Laravel 5.2.39 - Session flash not working

Hi, I have Laravel 5.2.39 and I try use status session message like this:

// Kernel
protected $middleware = [ \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class, ];

protected $middlewareGroups = [ 'web' => [

                \app\Http\Middleware\EncryptCookies::class,
                \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
                \Illuminate\Session\Middleware\StartSession::class,
                \Illuminate\View\Middleware\ShareErrorsFromSession::class,
                \app\Http\Middleware\VerifyCsrfToken::class,
],

// route
Route::group(['middleware' => 'web'], function () {
        Route::resource('posts', 'PostController');
});

// controller
return redirect()->route('posts.create')->with('status', 'Profile updated!');

// blade
@if (session('status'))
{{ session('status') }}
@endif

But it seems, that session not working well ...
