• code snippets works in localsystem.

• it’s not working prod enviornment.

php curl snippet

try {

    $runfile = 'http://103.16.101.52:8080/sendsms/bulksms?username=XXX&password=XXX&type=0&dlr=1&destination='. $row['phone_number'] . '&source=XXX&message='.$message;

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $runfile);

    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);

    $content = curl_exec ($ch);



    if(curl_exec($ch) === false)
    {
        echo 'Curl error: ' . curl_error($ch);
    }
    else
    {
        echo 'Operation completed without any errors';
    }
    var_dump($result);die;
    curl_close ($ch); 

    } 
    catch (Exception $e) {

    $message = $e->getMessage();
    print_r($message);
    die;
    }

• i googled and found

     CURLE_NOT_BUILT_IN (4)
  
     A requested feature, protocol or option was not found built-in in 
    this libcurl due to a build-time decision. This means that a feature 
     or option was not enabled or explicitly disabled when libcurl was 
     built and in order to get it to function you have to get a rebuilt libcurl.
  

• does this error belongs ipv4 or ipv6.

• im using cpanel please suggest.

Solution that worked for me

i tried with 80 port

  $runfile = 'http://103.16.101.52:80
