Php 登录到Adobe Connect时使用未知的SSL协议

我正在登录Adobe connect。我已经发送了这样的http请求

$ch = curl_init('https://emea2cps.adobeconnect.com/api/xml?action=login&login=nurgasemetey@gmail.com&password=D742455B61/');
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);
curl_exec($ch);
$info= curl_getinfo($ch);
echo 'passed' . $info['total_time'] . ' secconds ' . $info['url'] . '------ and http-code'. $info['http_code'];
print curl_error($ch);
curl_close($ch);

我收到了这样的回应

passed0.328 secconds https://emea2cps.adobeconnect.com/api/xml?action=login&login=nurgasemetey@gmail.com&password=D742455B61/------ and http-code0
Unknown SSL protocol error in connection to emea2cps.adobeconnect.com:443

我怎样才能解决这个问题

卷曲版本：7.29

php版本：5.4.12

原因是我没有添加以下内容

curl_setopt($ch1, CURLOPT_SSL_VERIFYHOST, FALSE);
