Unable to add new domain - api/v4 error

When I want to add a new domain to my Cloudflare account, I get the error shown in the image. It’s been like this for about 12 hours.

I also encountered the same problem. Unable to add new domain name.
The page rules are modified and do not take effect.
It’s been going on for a long time.

Same here and other problems too. Getting a lot of API errors


When will it get better? We added the domain, but it still gives the same error and we cannot use our site!
