vertica console dashboard - empty page [error?]

I have installed Vertica DB on my Debian. When i try open Vertica DB Overview, there is a empty page. I see this error in Chrome console 

jquery-2.1.0.js:8556 GET https://192.168.30.59:5450/webui/databases/1/overviewdash/11 500 (Server Error)

and when i try open Designer there is only:

String index out of range: 1 ... and empty page without UI elements.

Any hints?

Thanks
