PHP Laravel, Apache Server: "Curl ErrNo: 0. Curl Error: Failed to connect to my.website.com:443; Operation Now In Progress"

Question

我有一个带有 centos 发行版的 apache 服务器，我已经将 PHP Laravel 项目放在 git 上。它使用 cURL 请求来获取和执行从端点获取的数据。当我在我的本地虚拟机上运行时，它工作得很好。当我运行它在我的

这是我的代码，注意 cURL 请求：

//NOTE: $this->headers = ["Authorization: Bearer " . myServerAccessToken];
 //sets URL and $curl
 public function getAdmins() {
   $adminsURL = "https://my.test.instructure.com/api/v1/accounts/1/admins?per_page=20";
   $curl = curl_init();

   self::requestCurl($curl, $adminsURL, $this->headers);
   $resp = curl_exec($curl);
   //dd($resp); //shows false
   return self::setHeaders($curl);
 }

  //cURL request function: used to set the value of $curl as seen in other functions
 public function requestCurl($curl, $url, $headers) {
     return curl_setopt_array($curl, [
       CURLOPT_RETURNTRANSFER => TRUE,
       CURLINFO_HEADER_OUT => TRUE,
       CURLOPT_URL => $url,
       CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
       CURLOPT_SSL_VERIFYPEER => TRUE,
       CURLOPT_HTTPHEADER => $headers,
       CURLOPT_CUSTOMREQUEST => 'GET',
       CURLOPT_FOLLOWLOCATION => TRUE,
       CURLOPT_MAXREDIRS => 10, 
       CURLOPT_HEADER => TRUE
     ]);
   }


//returns "curl errno: 0. Failed to connect to my.test.instructure.com:443; Operation now in progress
 //gets the data from a successful curl request, and returns said data
public function setHeaders($curl) {
  echo "<h1>SetHeaders()</h1>";
  $resp = curl_exec($curl);
  $header_size = curl_getinfo( $curl, CURLINFO_HEADER_SIZE );
  $header = substr( $resp, 0, $header_size );
  $body = substr( $resp, $header_size); //$header_size
  $code = curl_getinfo($curl, CURLINFO_HTTP_CODE);
  if (curl_getinfo($curl, CURLINFO_HTTP_CODE) != 200) {
    echo "<h3>Curl errno: " . curl_getinfo($curl, CURLINFO_HTTP_CODE) . "</h3>";
    echo "<h3>Curl error(): " . curl_error($curl) . "</h3>";
    dd($body);
    return null; 
  }
  $data = json_decode($body, true);
  return $data;
}

我可以运行在我的本地机器上运行这段代码，而且它运行良好。无怨无悔，圆满成功。但是当我运行它在我的带有 centos 发行版的 apache 服务器上时，它崩溃了。这个输出是我得到的：

"SetHeaders()"
"Curl errno: 0"
"Curl error(): Failed connect to my.test.instructure.com:443; Operation now in progress"

"" [dd($body) returns an empty string]

我查过 currl errno: 0 和 curl error 443，但是我见过的与我的问题最接近的是这个页面：

How to resolve cURL Error (7): couldn't connect to host?

但据我所知，我的代码中已经有了建议的解决方案 (CURLOPT_FOLLOWLOCATION => TRUE)。

我怀疑问题出在服务器本身，但我对它的了解还不够多，无法说明什么。我查看了我服务器上的 /etc/hosts 文件夹，但我被告知它配置正确。考虑到这一点，我还能尝试什么来解决这个问题？

问题是我的服务器网络设置了代理。我可以通过在我的 curl_setopt_array 请求中添加两行来绕过它：

       public function requestCurl($curl, $url, $headers) {
           return curl_setopt_array($curl, [
             CURLOPT_RETURNTRANSFER => TRUE,
             CURLINFO_HEADER_OUT => TRUE,
             CURLOPT_URL => $url,
             CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
             CURLOPT_SSL_VERIFYPEER => TRUE,
             CURLOPT_HTTPHEADER => $headers,
             CURLOPT_CUSTOMREQUEST => 'GET',
             CURLOPT_PROXY => "https://my.proxy.url", //your proxy url
             CURLOPT_PROXYPORT => "my_proxy_port_number", // e.g 3333

             CURLOPT_FOLLOWLOCATION => TRUE,
             CURLOPT_MAXREDIRS => 10, 
             CURLOPT_HEADER => TRUE
           ]);
         }
