Why does Yandex Connect issue No MX records for this domain?

Question

Domain Name System

Essence:
There are two domains, one ns server has goddady, the second one has cloudflare. Decided to fasten incoming mail from Yandex. Mx, spf, dkim, cname, etc. records all stuck those that were registered in the Yandex connection in the dns management. Domains passed verification (verification was through txt in dns) - result: There are no MX records for this domain.
I googled a bit and decided to do this:
for one MX domain: mx.yandex.ru
for the second MX domain: mx.yandex.net
This also did not help.

Answer 1

Update of DNS records takes from 2 to 48 hours.

Answer 2

Answer 3

Like this:
mx.yandex.ru.
mx.yandex.net.

Answer 4

I also waited 72 hours, the domain was not updated. I wrote to Yandex Mail technical support and they manually updated the status of the MX record. After that the domain was attached.
