PHP with XMLRPC/SOAP hangs

Hello. I'm trying to access a webservice which supports both XMLRPC and SOAP on https://xxx.xxx.xxx.xxx:8080/, but it always hangs at curl_exec (i think) saying "Error, code 8: CURL error: couldn't connect to host".

I'm using PHP 5.2.1 with libcurl/7.15.3 OpenSSL/0.9.7a on a hosted web solution.

I've tried both NuSOAP: http://dietrich.ganx4.com/nusoap/ 
and PHP XMLRPC: http://phpxmlrpc.sourceforge.net/

All examples included in these libraries seem to work, but when I try on my own with the attached code snippet I get the response posted at the end of this post.

It seems like the webservice dosn't exists to PHP? But the webservice provider claims the service is up and running at https://xxx.xxx.xxx.xxx:8080/ (which answer when the URL entered directly in the browser, it's just PHP/CURL who don't seem to find it?)

Any idea what the problem could be? And what does the proxy parameters mean? Is this anything I need to fill out?

Response from NuSOAP when running attached code snippet:
