The certificate served over IPv6 is wrong
The certificate served over IPv6 at 2406:da1e:a87:67ff:6f38:5690:328f:1b68 isn't valid for xn--fiq737k.com: CERT_HAS_EXPIRED. Often the IPv6 address points at a different server (or an old one) than IPv4 does. Make sure 2406:da1e:a87:67ff:6f38:5690:328f:1b68 serves the same certificate as your IPv4 address.
