I have received this error when I execute code:
cURL Error #:Unknown cipher in list: tls_ecdhe_rsa_with_aes_256_cbc_sha
curl version:7.56.1
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_SSLVERSION,3);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_SSL_CIPHER_LIST, 'tls_ecdhe_rsa_with_aes_256_cbc_sha');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_VERBOSE,true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$xml = curl_exec($ch);
$err = curl_error($ch);
curl_close($ch);
$xmls = trim($xml);
echo $xmls;
echo "cURL Error #:" . $err;
How to solve this problem? And how to add or enable cipher tls_ecdhe_rsa_with_aes_256_cbc_sha?
