CloudKit.JS authentication is down

Cloudkit.js user authentication cannot work any more.

This causes one of my web apps which has been working for quite a few years stop to work. Can someone fix it?

You can reproduce the error with the official CloudKitJS catalog: https://cdn.apple-cloudkit.com/cloudkit-catalog/#authentication

Can someone help to look this issue? I believe it affects a huge number of users
