For some weird reason I'm unable to open icloud.com website, and unable to login to icloud app on Windows 10 laptop. As soon as I try to open icloud.com website, I get an error message when using Chrome, Edge (old and new) or IE11

Connection Error
iCloud encountered an error while trying to connect to the server.
When I try logging in into iCloud app with normal Windows install, or from Microsoft Store, I get the same error.
When I try opening icloud.com with Firefox, it loads fine, and I can login.

I tried cleaning all of the browsers data such as history, cookies, passwords with no success.
It happens only on one Lenovo laptop. All other devices don't have this issue.
I'm using Windows 10 x64 1909 with all the latest updates.
Computer time zone and date/time is correct
I played with Windows Security settings with no success.
There's no other antivirus installed.
I can login to iTunes software using my apple account just fine.
So somehow Windows is blocking icloud access.
Any suggestions? Thanks.
