Authentication request into a Docker container

Hi all,

I'm trying to use SoapUI Open Source to do some simple testing of some web services.  Our standard development environment is built inside a docker container.  If I enter the WSDL location

http://bank:7047/NAV/WS/California/Codeunit/GetNAVData

I am prompted for my credentials.  However, I get this error returned:

Error loading [http://bank:7047/NAV/WS/California/Codeunit/GetNAVData]: org.apache.xmlbeans.XmlException: org.apache.xmlbeans.XmlException: error: Unexpected end of file after null

I can enter the same URL into a normal browser window and it retrieves the WSDL.  I can also use browser-based tools such as Wizdler to retrieve WSDL and submit "Post" and "Get" transactions.

If I access our shared test environment which is NOT in a Docker environment (i.e. just another server on our network), my credentials work fine and the WSDL is returned.

I tried a demo of SoapUI Pro, and I was able to get it to work with Docker.  I'm just wondering if there's a setting in SoapUI Open source that allows authentication into Docker containers?

Thanks,

Ron
