Error "_acme-challenge.site.ru - check that a DNS record exists for this domain" when installing a wildcard certificate from lets encrypt?

Question

Digital certificates

I enter the command in the terminal:

certbot certonly --manual --preferred-challenges dns --server https://acme-v02.api.letsencrypt.org/directory --manual-public-ip-logging-ok -d '*.site.ru' -d site.ru

An error occurs:

Waiting for verification...
Challenge failed for domain site.ru
dns-01 challenge for site.ru
Cleaning up challenges
Some challenges have failed.

IMPORTANT NOTES:
 - The following errors were reported by the server:

   Domain: site.ru
   Type:   dns
   Detail: DNS problem: NXDOMAIN looking up TXT for
   _acme-challenge.site.ru - check that a DNS record exists
   for this domain

When I check the TXT record, then:

;; ANSWER SECTION:
site.ru.        86400   IN      TXT     "_acme-challenge.site.ru=ZIgjpsHA1P8uyrnyAa5fSzT3thLe4q0sBn5dxPTmEeE"

Answer 1

# host -t txt site.ru.
site.ru has no TXT record

Answer 2

And the answer should be

_acme-challenge.site.ru 300 IN TXT "ZIgjpsHA1P8uyrnyAa5fSzT3thLe4q0sBn5dxPTmEeE"

Such an entry must be added to the list of entries on your DNS server to which the domain is delegated.
