strange behavior of pg_hba.conf file

no pg_hba.conf entry for host "::1", user "postgres", database "postgres

The entry of pg_hba.conf is like below:

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only

local   all           all                                          scram-sha-256

# IPv4 local connections:

host    all           postgres     127.0.0.1/32               scram-sha-256

What I am missing here, please suggest.
