HybridAuth Codeigniter 3

I installed HybridAuth 2.8 using composer and I'm trying to use it with CodeIgniter 3.

I created a library which is extending Hybrid_Auth.

class MY_HybridAuth extends Hybrid_Auth {

   function __construct($config = []) {
       $this->_CI =& get_instance();
       $this->_CI->load->helper('url');
       $config = $this->_CI->config->item('hybridauth');
       $config['base_url'] = base_url() . $config['base_url'];
       parent::__construct($config);
   }
}

My controller :

public function social($provider) {
    $provider = ucfirst($provider);
    log_message('debug', "controllers.Auth.social($provider)");
    // TODO Handle missing parameter properly
    if (!isset($provider)) redirect('login', 'location');
    try {
        if ($this->HybridAuth->is_provider_enabled($provider)) {
            $service = $this->HybridAuth->authenticate($provider);
            var_dump($service->getUserProfile());
        }
    } catch (Exception $e) {
        var_dump($e);
    }
}

public function endpoint() {
    if (isset($_REQUEST['hauth_start']) || isset($_REQUEST['hauth_done'])) {
        Hybrid_Endpoint::process();
    }
}

My problem is :

When the user is redirected to /login/social/endpoint?auth.start..., HybridAuth appends the current url to the new one (localhost/login/localhost/login/social/endpoint?auth.start...).

HybridAuth is using header("Location: $url") to redirect the user. I setted my base_url to localhost. My HybridAuth endpoint is : base_url() . /login/social/endpoint, which is handled by the endpoint method in above controller.

May someone help ?
