Magento 2 Rest Api call curl SSL Error

Question

I have setup a custom Magento Rest Api at the endpoint: "https://domain-name.de/rest/V1/wawi". This Api just returns a simple json string. Have tested my Api with Postman application -> works fine.

The problem occurs, when I test it in PHP script:

 $curl = curl_init();
 curl_setopt_array($curl, array(
 CURLOPT_URL => "https://domain-name.de/rest/V1/wawi",
 CURLOPT_RETURNTRANSFER => true,
 CURLOPT_ENCODING => "",
 CURLOPT_MAXREDIRS => 10,
 CURLOPT_TIMEOUT => 30,
 CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
 CURLOPT_SSL_VERIFYPEER => 0,
 CURLOPT_SSL_VERIFYHOST => 0,
 CURLOPT_CUSTOMREQUEST => "POST",
 CURLOPT_POSTFIELDS => "{\"p\":\"test\"}",
 CURLOPT_HTTPHEADER => array(
 "cache-control: no-cache",
 "content-type: application/json",
 ),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
 echo "cURL Error #:" . $err;
} else {
 echo $response;
}

RESULT:

cURL Error #:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

Any ideas on how to solve this issue ?

EDIT Just checked my magento server is using "OpenSSL 1.0.1e-fips 11 Feb 2013 openssl version number: 268439647" and my client is using "OpenSSL 1.0.1k 8 Jan 2015 openssl version number: 268439743"

Answer 1

Answer 2

I don't see any reason for using the following lines:

 CURLOPT_ENCODING => "",
 CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
 CURLOPT_ENCODING => "",

Try removing all these lines, or, if you prefer, test removing one by one.
