port 80 of ipv6 on srv0.ietf55.ops.ietf.org

55th IETF network staffs,

i have a trivial trouble about ipv6 accessing the page "Host Information"
on 55th IETF web because IPv6 port 80 on www.ietf55.ops.ietf.org
looks closed.
i would be happy if you opened the port of IPv6 or removed AAAA record
from the DNS.

thank you.
