Cloud connection is unavailable

Hi all,

I did not realize my hubitat was set to use google dns hardcoded in the settings. I changed it to use my Rasp-pi dns and rebooted it. Upon reboot, everything is working, however, i get "Cloud connection is unavailable.". I checked my rasp-pi for any blocks, but don't see any. But i'm guessing it's blocking something it shouldn't be.

Is there a list of servers/domains/etc somewhere i can whitelist on my rasp-pi?
