Many emails about: "TLS certificate renewal was unsuccessful"

I received eight emails like this recently, but I do have IPv6 addresses pointed at them. Does anyone know how to check if something is wrong?

We recently tried to provision a certificate for the domain example.com in your app app-name, but were unable to do so.

Here is the error message we received when provisioning your certificate:

An IPv6 address pointed at us is required.

The sites are online and there are IPv6 addresses pointed at them.

Hi… As just a quick pointer…

Thanks, that must be it then. Everything looks okay. There are AAAA records.
