why CC cannot be used if no internet connection topic

Hi Expert,

just wondering why CC is not working if we have no internet connection. for example for last several days I have a problem with my ISP and
we dont have internet connection but our local WIFI is working, and I was noticed when we have no internet CC is not working (I cannot play movie locally through extension or even cast photo using BubbleUPnP).

is it normal like this? I have rooted CC using latest eureka image.


Thanks
