Evidently, your DNS setup is resolving the machine's name as a IPv6
address, whereupon PG quite legitimately doesn't find a match in
its pg_hba table. (I suppose you are using listen_addresses = "*",
else the server wouldn't even be listening on this address.)

Looking at the "hosts" entry in /etc/nsswitch.conf might help figure out
exactly what's going on, but I'll bet a nickel that this is some
unhelpful systemd behavior.
