PHP Error: Parsing WSDL: Couldn't load from...

[Anonymous]

I can access the WSDL via this URL in my browser:
    https://504-iva-042.mktoapi.com/soap/mktows/2_3?WSDL

But when the following executes I get the 'couldn't load from' error:
 

    $soapClient = new SoapClient('https://504-iva-042.mktoapi.com/soap/mktows/2_3?WSDL', $options);

Any tips?


TIA
