Login redirecting in cakePHP 3.4

I'm trying to redirect to current page after logged in, using cakephp 3.4 but I'm getting like this

localhost page isn't working, locahost page redirecting you too many times. Try clearing your cookies

for 2 sec after that it's redirecting to home page. Please help me out here. Here my code

In appController.php

public function initialize()
{ 
    parent::initialize();
    $this->loadComponent('RequestHandler');
    $this->loadComponent('Flash');
    $this->loadComponent('Auth', [
        'authorize' => ['Controller'],
        'authenticate' => [
            'Form' => [
                'fields' => [
                    'username' => 'email',
                    'password' => 'password'
                ],
                'scope' => ['userStatus' => '1']
            ]
        ],
        'loginAction' => [
            'controller' => 'Users',
            'action' => 'login'
        ],
        'unauthorizedRedirect' => $this->referer(),
        'logoutRedirect'       => [
                'controller' => 'Users',
                'action'     => 'login'
        ]
    ]);
}

In loginController.php

function login{ 
 if ( $this->request->is( 'post' ) ) {
    if ( $this->Auth->login() ) 
    {
       $this->redirect($this->referer());
    } 
    else {
      $this->Flash->error(__('Your username or password is incorrect.'));
    }
  }
}
