无法使用肥皂连接到橙色m2m

I am trying to create a soap connection using the standard php soap client and I believe it is all correctly coded, however I am receiving this error :

 Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://m2mconnect.orange.co.uk/orange-soap/services/MessageServiceByCountry?wsdl' : Start tag expected, '<' not found in C:\wamp\www\phpun.php:16 Stack trace: #0 C:\wamp\www\phpun.php(16): SoapClient->SoapClient('https://m2mconn...') #1 {main} thrown in C:\wamp\www\phpun.php on line 16

From what I have found online it seems one problem may be to do with the ports, however im not sure which ports to check/use or how to.

Im also unsure if it is something to do with my internet connection as it is a little strange being from one router to another.

Here is my code:

$client = new SoapClient("https://m2mconnect.orange.co.uk/orange-soap/services/MessageServiceByCountry?wsdl");
