来自Godady服务器的EC2实例的卷曲请求拒绝连接

Question

当我从godady的服务器向EC2实例发送curl请求时，每次我都会收到连接拒绝错误。但是，当我从另一台服务器或localhost尝试相同的代码时，它的工作正常。

$ch = curl_init();
//curl_setopt($ch, CURLOPT_PROXY,$proxy_IP);
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
$output=curl_exec($ch);
if(curl_errno($ch))
{
    echo 'Curl error: ' . curl_error($ch);
}

curl_close($ch);
echo '<pre>';print_r($output);
