Nothing keeping you from an A

  1. The certificate served over IPv6 is wrong
    The certificate served over IPv6 at 2607:f8b0:4004:c08::88 isn't valid for youtube-nocookie.com: ERR_TLS_CERT_ALTNAME_INVALID. Often the IPv6 address points at a different server (or an old one) than IPv4 does. Make sure 2607:f8b0:4004:c08::88 serves the same certificate as your IPv4 address.
