Nothing keeping you from an A

The certificate served over IPv6 is wrong
The certificate served over IPv6 at 2a03:4000:61:a81d::21:2187 isn't valid for xn--grisch-wxa.com: CERT_HAS_EXPIRED. Often the IPv6 address points at a different server (or an old one) than IPv4 does. Make sure 2a03:4000:61:a81d::21:2187 serves the same certificate as your IPv4 address.
