Fix the unreadable CAA record on Cloudflare
Why it matters
A CAA record has a value that cannot be parsed, so a certificate authority may treat it as an error and refuse to issue or renew your certificates. A stray quote, space or missing value is enough.
Staged change. Do this in stages and check each one before the next, so a mistake does not break your site or your mail.
The fix
- Open DNS then Records, find the CAA record and edit it. Choose the tag from the dropdown and enter only the CA's domain in the value field, without quotes.
- Run a certificate renewal test afterwards.
