Error when loading protected wsdl file with authorization

Hi All,

I get this error logs when tried to load wsdl url, the wsdl url is the protected wsdl so the user need to insert authorization before viewing the xml code inside.

It's working in the browser but not in the SOAP UI. is there any steps i missed to test this url?
