Netlify site name: cheery-chimera-2ef95a.netlify.app
custom domain: desingbuero.de
I pointed the apex domain and the www-subdomain from desingbuero.de to netlify. It seems to work for the subdomain, but the certificate now makes problems with the following error:
This is using HTTP verification method and not the DNS verification method. The HTTP verification failed because the IPv6 IP address 2a00:1828:1000:2428::2: is not one that Netlify controls.
In order for Netlify to provision the SSL all non-Netlify IP address records must be deleted for any domain names being delegated to Netlify. This would mean removing both AAAA records above and the A record for 89.238.73.28.
If that doesn’t resolve the issue, please let us know.
