SOAP-ERROR: Parsing WSDL: Couldn't load from 'https

Question

Why can´t load PHP a extenal SOAP entity? The Error: SOAP-ERROR: Parsing WSDL: Couldn't load from

My fist idea: Can php accept a extenal https document?

Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://soatest.paysafecard.com/psc/services/PscService?wsdl' :
failed to load external entity "https://soatest.paysafecard.com/psc/services/PscService?wsdl" in /var/www/virtual/example.com/htdocs/class.php:791

I had the same error and fixed it by contacting paysafe integration@paysafecard.com. They actually added my server's Ip address in their white lists.
