CAA forbids all certificate issuance
NOTEWhat it means
example.com publishes issue ";" which tells every certificate authority to refuse. That is a valid and deliberate lock. It also means nobody can renew a certificate here, including you.
How to fix it
No action needed if that is intended. To allow renewals, add a CAA record naming the CA you use.
Check your own domain
This page describes the condition. To find out whether your domain has it, run the CAA test or the full checkup, which examines every record at once.
Understand it properly
This page covers one condition. For the whole picture, DNSSEC and certificate authority records, or start at the Health Library.
Where this comes from
We judge this against RFC 8659 section 4.2. Every finding on this site cites the specification behind it so you can check the work rather than take our word for it.

Every fix on this site is yours to implement. If you would rather someone did it, I take this work directly.
