Client Authorization not work global

I noticed that Client Authorization stopped working, I couldn’t log in to sites that support this authorization, my friends also couldn’t do it. I think there is a problem with this service.
Try to run a test, you will be told that the key cannot be used, although this site worked until the last browser update.

We conducted tests and realized that the latest browser update does not allow authorization through Client Authorization, but the keys that were added before the update work.

Hello, yesterday I also wanted to enable Client Authorization on my Hidden Service. I have done this several times before, but this time it just didn’t work.

I can no longer connect to the server and get the error message XF2.

Is there currently a known problem?
I tried to set it a few times, but it never worked.
