Call Quality Dashboard for Skype for Business Server 2015 issue

Hi,

I deployed Skype for business server 2015 and Call Quality Dashboard for Skype for Business Server 2015.  

I am facing issue When I open the portal page is accessible via http://xy.abc.com/CQD

Then I get the page message  Loading.. only dashboard is not showing any information.

Any idea.

Thanks,

Deepak .
