This looks like a configuration error in your DNS. FE80:... is a
link-local address, and you generally don't want them in DNS. Either
remove that completely (as others have already suggested) or replace if
with the global unicast (or at least unique local) IPv6 address (and
then add that to pg_hba.conf).

If the address isn't in DNS, check your /etc/hosts.
