It is impossible to add a SOAP Webservice in Dollar Universe Manager for Web Services in case the wsdl is protected and requires a User / Password to be able to download it.
The error that appears in the Univiewer Console is:
Error while loading WSDL for service WEBSERVICE_NAME. The error is: WSDLException (at /html): faultCode=INVALID_WSDL: Expected element '{http://schemas.xmlsoap.org/wsdl/}definitions'.
Component : Dollar Universe Manager for Web Services (JEE) 6.x and 7.x
Unsupported feature in Dollar Universe Manager for Web Services
Unsupported feature, the manager for Web Services cannot retrieve wsdl-file if a username and password are necessary to download the wsdl-file.
As a workaround, you can download the wsdl-file locally and then copy it into the Dollar Universe folder to be able to use it inside the SOAP Uprocs:
For SoapUI default timeout for HTTP requests is 0, please update it to allow definitions to load:
SoapUI - File -> Preferences -> HTTP Settings -> Socket Timeout -> set to high number like 100000 ms
https://www.soapui.org/docs/preferences-and-settings/?sbsearch=Socket%20Timeout
This will make sure issue is not with HTTP Socket timeout.
