try remove web middleware if you're using 5.2.27 or higher. thing laravel automatically applies web middleware routes inside routes.php , if you're trying add manually can errors.

app/providers/routeserviceprovider.php of 5.2.27 version adds web middleware routes inside routes.php:

protected function mapwebroutes(router $router) {     $router->group([         'namespace' => $this->namespace, 'middleware' => 'web',     ], function ($router) {         require app_path('http/routes.php');     }); }
