Sign in with Apple Authentication Error

I did create simple CloudKit JS app too access cloudKit records. Everything work fine for few months, but last week i can not uthanticate anymore. I get Authentication Error, on console i can see more details. It says:

Refused to connect to https://setup.apple-cloudkit.com/.... because it does not appear in the connect-src directive of the Content Security Policy.


I have tried on different machines, browsers, clearing cache and so on. No success. I can sign in to my developer sites, without any problems.

Funny thing is that the same account is keeping me connected to cloudKit on iOS device safari - it works there so far.


Have no idea where to look for reason. Have anyone same issue ?

Unfortunately, I have the same issue since a few days.


EDIT (2019-09-13):

This issue seems to be resolved for my CloudKitJS apps today.
