Adding external www yields HTTP 301 ./ #62

I try to start client-application-0.0.6 on a windows workstation.
I adjust config.yaml and point to it at startup.

ui:
  enabled: true
  directory: "/c/Users/habj/xr/ndu-web-gui/dist/ndu-web-gui"

Whwn accessing index.html (available in directory above) I expect to download .html file (HTTP status 200) but get HTTP 301, location ./ (using curl).

Any idea on what to do to enable my web UI service?

$ curl -v http://localhost:8080/index.html
