Ошибка в скрипте с curl

$postdata = array(
        'login' => $this->HD_login,
        'password' => $this->HD_password,
    );
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $this->HD_url . "/ptn/hd_auth");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 60);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
    curl_setopt($ch, CURLOPT_COOKIEJAR, "cookieHD.txt");
    $result = curl_exec($ch);
    print_r(curl_getinfo($ch));
    curl_close($ch);

В $result пусто curl_getinfo показывает

[url] => http://127.0.0.1:2266/ptn/hd_auth

В чем может быть косяк?
