  1. The certificate served over IPv6 is wrong
    The certificate served over IPv6 at 2a06:dd00:1:4::105 isn't valid for kolchin.tech: ERR_TLS_CERT_ALTNAME_INVALID. Often the IPv6 address points at a different server (or an old one) than IPv4 does. Make sure 2a06:dd00:1:4::105 serves the same certificate as your IPv4 address.
