  1. The certificate served over IPv6 is wrong
    The certificate served over IPv6 at 2a02:4780:c6:3a96::1 isn't valid for kairossystem.tech: ERR_TLS_CERT_ALTNAME_INVALID. Often the IPv6 address points at a different server (or an old one) than IPv4 does. Make sure 2a02:4780:c6:3a96::1 serves the same certificate as your IPv4 address.
