Can't add custom domain to Cloudflare Pages

I am getting an errors on the second step (Configure DNS) when adding a custom domain to Cloudflare Pages. I tried to clear the records myself, but it doesn’t help at all. Also, domain contains punycode, maybe it’s related somehow.

Error codes: 8000000, 81044.
