Every time I click to go to another page, it asks for the login again (LARAVEL 5.6)

Good afternoon guys

Every time I go to another page, my application asks to re-login

Follow the route

Route::get('/', function () {
    return view('welcome');
});



Auth::routes();

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

    Route::get('/create', 'CreateController@create')->name('create');
    Route::get('/query', 'CreateController@query')->name('query');
    Route::get('/detalhes', ['as'=>'detalhes', 'uses'=> 'CreateController@detalhes']);
    Route::get('/tarefas', ['as'=>'tarefas', 'uses'=> 'CreateController@tarefas']);
    Route::post('/store', ['as'=>'store', 'uses'=> 'CreateController@store']);
    Route::post('/delete', ['as' => 'delete' , 'uses' => 'CreateController@delete']);
    Route::post('/alterar', ['as' => 'alterar' , 'uses' => 'CreateController@alterar']);
    Route::post('/update', ['as' => 'update' , 'uses' => 'CreateController@update']);

});

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

Controller home:

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class HomeController extends Controller
{
    /**
     * CreateController a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('auth');
    }

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        return view('home');
    }
}
