SOAP::Lite Hangs on SSL request

[cbeels]

The client code is

#install SOAP-Lite and MIME-tools packages
use SOAP::Lite 'trace', 'debug';
 
#override version
SOAP::Lite->soapversion('1.2');
 
#override credentials     
sub SOAP::Transport::HTTP::Client::get_basic_credentials { 
  return 'USER' => 'PW';
}
 
my $result = SOAP::Lite 
    ->uri('urn:RiskMetricsDirect:1.0:wspone-service')
    ->proxy('https://ws.uat.riskmetrics.com/wsproxy/basic', timeout => 5)
    ->ListPortfolios()
    ->result;
 
print $result;    

When it runs, it prints the following, then hangs. If run without credentials, it gets a fobidden message, and I am maxing out my queries, so the login is definitely working.

SOAP::Transport::HTTP::Client::send_receive: POST https://ws.uat.riskmetrics.com
/wsproxy/basic HTTP/1.1
Accept: text/xml
Accept: multipart/*
Accept: application/soap
Content-Length: 443
Content-Type: application/soap; charset=utf-8
SOAPAction: "urn:RiskMetricsDirect:1.0:wspone-service#ListPortfolios"
 
<?xml version="1.0" encoding="UTF-8"?><soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soapenc="http://www.w3.org/2003/05/soap-encoding" xmlns:xsd="http://www.w3.org/2001/XMLSchema" soap:encodingStyle="http://www.w3.org/2003/05/soap-encoding" xmlns:soap="http://www.w3.org/2003/05/soap-envelope"><soap:Body><ListPortfolios xmlns="urn:RiskMetricsDirect:1.0:wspone-service" xsi:nil="true" /></soap:Body></soap:Envelope>

When I copy the above request into soapui (www.soapui.org), it goes through just fine. Any ideas are appreciated!

Thanks,
