Nothing when I navigate to Ranger Admin console

Hi,

When I navigate to the Ranger Admin console in Chrome, I get an empty page, no login, nothing at all. Same happens in Firefox, and I get HTTP 404 Page not found in IE.

I started all services from the Ambari console, and restart the Ranger system from command line with root. I still can’t log in Ranger.

Do you know how to fix this issue?

Details:
URL Ranger Admin console: http://192.168.23.128:6080/
HDP 2.3 Sandbox for VMWare
Chrome 45.0.2454.101
IE 9
Firefox 40.0.3

Thanks,

Celia
