Windows 10 machines have the ability to set the networks they are connected to as "Private" or "Public". When set to public the Windwos 10 machine will have different security standards and discoverability on the network. You can read more about this feature here.
Known issue: "Public" Networks, IPv6, and Circle
You might encounter IPv6 connection issues when using a Windows 10 Machine managed by Circle if you've set the Wi-Fi connection as "Public". We instead recommend making sure the network connection is set to "Private" so the machine can resolve IPv6 connections correctly.
This issue occurs because of the different security standards Windows 10 applies to "Public" networks. Circle is looking to resolve this but for now turning the network to "Private" should resolve this issue.
How Do I Set a Network to "Private"?
- On the right side of the taskbar, select the Wi-Fi network icon.
- Under the name of the Wi-Fi network that you’re connected to, select Properties.
- Under Network profile, select Public or Private.
