Why is my game connecting to config.uca.cloud.unity3d.com on startup after recent Unity update?

I don’t understand what’s happening here, and so I’m looking for some advice.

I just updated my Unity build from 5.1.1 or so to 5.5.2 and after building my game and running it in Steam I’m now getting a Firewall warning from Norton360 that I’ve never gotten before the update. My game doesn’t feature any online multiplayer modes or anything and isn’t supposed to connect to the internet in any way.

I’ve done google and answers searches for “config.uca.cloud.unity3d.com” but quite incredibly found nothing. Why is this happening and how can I stop the game from making this internet connection to config.uca.cloud.unity3d.com?

Thanks for any help!

Turns out the answer is Unity collecting anonymous Hardware Stats from players when the game launches, which can’t be disabled with Unity Personal.

Unless you’re a developer, you can just edit your hosts file and make it not resolve to any IP address.

c:\Windows\System32\drivers\etc\hosts
0.0.0.0 config.uca.cloud.unity3d.com
0.0.0.0 cdp.cloud.unity3d.com,Unless you’re a developer, you can just edit your hosts file and make it not resolve to any IP address.
