Curl 在拨打电话时似乎会挂起。这会破坏 wordpress/wp-admin 网站和用于 IP-SMS 的 twillio 帮助程序库。
安装 vsftpd 并创建新用户后出现此问题。
测试 curl 的脚本：（来自谷歌）
function nxs_cURLTest($url, $msg, $testText){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.73 Safari/537.36");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
$response = curl_exec($ch);
$errmsg = curl_error($ch);
$cInfo = curl_getinfo($ch);
curl_close($ch);
echo "Testing ... ".$url." - ".$cInfo['url']."<br />";
if (stripos($response, $testText)!==false)
echo "....".$msg." - OK<br />";
else
{
echo "....<b style='color:red;'>".$msg." - Problem</b><br /><pre>";
print_r($errmsg);
print_r($cInfo);
print_r(htmlentities($response));
echo "</pre>There is a problem with cURL. You need to contact your server admin or hosting provider.";
}

Curl 仍然安装在我的服务器上，我已经通过以下方式验证了这一点phpinfo();
重新安装 curl 模块没有帮助。
sudo apt-get install php5-curl
sudo service apache2 restart

Failed to connect to X port 443: Connection timed out
这看起来更像是网络问题，而不是phpand/or curl，应该尝试通过 shell 的curland/or来复制它wget。
