The certificate served over IPv6 is wrong
The certificate served over IPv6 at 2a00:d70:0:a::166 isn't valid for xn--fhl-bar-n2a.com: ERR_TLS_CERT_ALTNAME_INVALID. Often the IPv6 address points at a different server (or an old one) than IPv4 does. Make sure 2a00:d70:0:a::166 serves the same certificate as your IPv4 address.
