Пошук записів CAA

Записи CAA визначають, які центри сертифікації можуть видавати HTTPS‑сертифікати для імені. Неправильний запис CAA — поширена причина невдалого оновлення сертифікатів Let’s Encrypt.

Записів: Reading CAA

0 issue "letsencrypt.org" – Let’s Encrypt may issue normal certificates.
0 issuewild "sectigo.com" – Sectigo may issue wildcard certificates.
0 iodef "mailto:security@example.com" – where CAs report refused requests.

If a name has no CAA records, CAs check its parent names up to the domain. If none have any, every CA may issue.

Fixing “CAA record prevents issuance”

Add an issue record for the CA you actually use, or remove restrictive records you no longer need. Then request the certificate again.

Frequently asked questions

Do I need CAA records?

No, they are optional. They add protection by stopping other CAs from issuing certificates for your domain.

Which value do I use for Let’s Encrypt?

0 issue "letsencrypt.org". Add issuewild as well if you use wildcard certificates.
