Curl requests the https URL, which causes the connection to be reset after I open the web page.

Today, I deployed an older program on Alibaba Cloud, using Alibaba Cloud's esc. The environment is as follows:

• PHP Version 5.2.17

• Apache/2.2.29 (Unix)

• Mysql 5.1.73

The index.php file contains the following code

<code>$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,'http://www.baidu.com/');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
//curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
//curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$info = curl_exec($ch);
curl_close($ch);
echo $info;</code>

When I visit domain name/index.php, the Baidu page appears normally.
But after I made some modifications, the connection was reset and the connection was reset. I searched online and found no effective solution.

<code>$ch = curl_init();

curl_setopt($ch,CURLOPT_URL,'https://www.baidu.com/');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$info = curl_exec($ch);
curl_close($ch);
echo $info;</code>

What causes this problem? Is it a php version problem or some other reason? Thank you for your help!
