Problem with Preprod

[yoandm]

Hi,
I got this error when using preprod.
Uncaught Zend\Http\Client\Adapter\Exception\RuntimeException: Error in cURL request: error:14077102:SSL routines:SSL23_GET_SERVER_HELLO:unsupported protocol

The problem seems to be in sdk/src/core/HttpTools/CDSApiSoapRequest.php (line 70).
CURLOPT_SSLVERSION => 4

Preprod only support v1 no ?
If I put a CURLOPT_SSLVERSION => 1 it's ok.

The best option seems to upgrade preprod server or to test API mode to use the good version in the sdk.

Same issue over here, as @yoandm says, changing CURLOPT_SSLVERSION from 4 to 1 makes preprod work.
