Can't connect to WSDL via https on PHP 5.5

Hi! I have written a small php library for some SOAP functions in a wsdl file and it works perfectly with PHP 5.4.16. However, with version 5.5 the connection won't work, I get the following error: SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://<myServer>/query.jws?WSDL' : failed to load external entity "https://<myserver>/query.jws?WSDL" My old code looks like this: $this->soap = new SoapClient($this->getAPIURL(QUERY)); return $this->sendSOAP('hello', $params); and, as already said it works perfectly fine on PHP 5.4. Now I found that on version 5.5 there is a new option "ssl_method". It looks like it has no effect whatsoever, because the result is always the same, regardless which option I put. Also the default value is the same as in PHP 5.4. However, I changed my code to this but without success: try { $this->soap = new SoapClient($this->getAPIURL(QUERY),

    array (
      "ssl_method" => "SOAP_SSL_METHOD_SSLv23"
    )

); } catch (SoapFault $f) { print $f->faultstring; } I am using php 5.5.6 via XAMPP on my Windows machine. Does anyone have any idea what I might do wrong? Or could it be a bug in the newest PHP version? Thanks and best regards Tobias
