Does anything show up in the postmaster log when you do that?
I'm a bit suspicious that PGAdmin4 is trying to use an IPv6 definition of
"localhost" and you've only made provision for IPv4 in pg_hba.conf, or
something like that.
It's regrettable that PGAdmin4 isn't giving you more detail about the
failure, but you need to complain about that on the pgadmin lists,
not here --- this list is for server problems.
