1- Open webbrowser

2- Open developper tools, go on network tab

3- Open url https://uui.api.simpledemo.onap.org:30398/usecase-ui/#/home

4- on network tab, each request to path /api/usercaseui-server/v1 return 404 error (cf attached capture)

Request to backend server seems handled by tomcat frontend server instead of tomcat backend server.

Backend server is up and running and responding to direct curl request (example curl https://uui.api.simpledemo.onap.org:30399/api/usecaseui-server/v1/uui-lcm/serviceNumByCustomer -k)

Jira created following mrichomme, sdesbure and eric.debeau advice.
