Try running the following test script, to see what version TLS your cURL is using to connect with:

<?php 
$ch = curl_init('https://www.howsmyssl.com/a/check');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
curl_close($ch);

$json = json_decode($data);
echo $json->tls_version ."\n";

Reason what curl used TLS 1.0, because of was old curl version (earlier 7.34)

Thank you so much
