Gateway time out CI 4.4.1

Start with a simple one. 
Comment out the routes except for one + SQL call code and show an empty template. Then uncomment the requests.

PHP Code:

    public function admin_rutinas()
    {
        $user_id    =$this->request->getGet('id');

        // $admin_model= new Admin_users_model();
        // $user_name=$admin_model->get_username($user_id);

        $data['user_name']='Username';
        $data['user_id']=$user_id;
        $data['content_view']="admin/admin_rutinas_view";
      
        return view('admin/admin_main_view',$data);
    }

//$routes->get('admin_start',  'Admin::index');
//$routes->get('admin_ejercicios',  'Admin::admin_ejercicios');
$routes->get('admin_rutinas',  'Admin::admin_rutinas');
