Connection Error iCloud encountered an error while trying to connect to the server

I have been logging into https://www.icloud.com/mail/ successfully for a year but recently I get the connection error instead of a prompt to enter credentials.

Windows 10 Chrome. Same problem with Microsoft Edge.

I can login on with another computer connected to the same network.

I can log on with Chrome on my iPhone.

I have restarted the computer, cleared cache, and wasted an hour with Apple tech support.

Newsflash - found this suggestion from a few days ago (disable IPv6 in internet connection config) and it worked!

I was having this issue on a Windows PC. This video's solution is the only thing that worked for me. In case the video doesn't work for you:

1. Type ncpa.cpl into your Windows search bar. Click on the resulting "Control panel item" which should bring you to this screen:
2. Whatever your active network adapter is (wireless card, ethernet adapter), right click it, click Properties, then uncheck IPv6 setting, like below. Note: if you're plugged into ethernet and your wireless card is connected, you want to change this setting on whichever connection is active. Typically the ethernet will be active if both ethernet and wireless card are connected.
3. Try icloud.com again.

I'm not a tech expert, but this seems to suggest Apple has a configuration issue they need to change.

[derB]: well, duh
