cURL error 35 - Unknown SSL protocol error in connection to api.rkd.reuters.com:443

I had this problem, and I fixed it by setting the curl SSL version to version 3

curl_setopt($ch, CURLOPT_SSLVERSION,3);

Apparently the server started requiring SSL version 3, and this setting caused cURL with SSL to start working again.

Fixed it! It's a known problem with Ubuntu 12.04

-- Cancel that, it just disabled exceptions, this is still not working! HELP!

-- EDIT - HERES HOW I FIXED IT IN THE END!

I upgraded to PHP 5.5 from 5.4.3 and set the following options in my call, which fixed it:

$options = array('ssl_method' => SOAP_SSL_METHOD_SSLv3,'soap_version' => SOAP_1_2);$sc = new SoapClient('https://my-url.com/call/', $options);

The upgrade was necessary because the constant SOAP_SSL_METHOD_SSLv3 isn't present in PHP versions < 5.5, and unfortunately Ubuntu Server at the time would only allow an upgrade to 5.4.3 through apt-get update php5. I manually installed the later version, and it works fine now.

I had the same problem, unfortunately with a host unwilling to upgrade to php 5.5.

I solved it by creating a new class extending php's SoapClient to use cURL:

/** * New SoapClient class. * This extends php's SoapClient, * overriding __doRequest to use cURL to send the SOAP request. */class SoapClientCurl extends SoapClient {  public function __doRequest($request, $location, $action, $version, $one_way = NULL) {$soap_request = $request;$header = array(  'Content-type: application/soap+xml; charset=utf-8',  "Accept: text/xml",  "Cache-Control: no-cache",  "Pragma: no-cache",  "SOAPAction: \"$action\"",  "Content-length: " . strlen($soap_request),);$soap_do = curl_init();$url = $location;$options = array(  CURLOPT_RETURNTRANSFER => true,  CURLOPT_HEADER => FALSE,  //CURLOPT_FOLLOWLOCATION => true,  CURLOPT_SSL_VERIFYHOST => 0,  CURLOPT_SSL_VERIFYPEER => FALSE,  CURLOPT_RETURNTRANSFER => TRUE,  //CURLOPT_USERAGENT => 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)',  CURLOPT_VERBOSE => true,  CURLOPT_POST => TRUE,  CURLOPT_URL => $url,  CURLOPT_POSTFIELDS => $soap_request,  CURLOPT_HTTPHEADER => $header,  CURLOPT_FAILONERROR => TRUE,  CURLOPT_SSLVERSION => 3,);curl_setopt_array($soap_do, $options);$output = curl_exec($soap_do);if ($output === FALSE) {  $err = 'Curl error: ' . curl_error($soap_do);}else {  ///Operation completed successfully}curl_close($soap_do);// Uncomment the following line to let the parent handle the request.//return parent::__doRequest($request, $location, $action, $version);return $output;  }}
