pg_hba.conf : bad entry for ADDRESS

I am deploying mattermost on my machine following their documentation[0].

My machine network settings:
----------------------------------
$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
group default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: host0(at)if4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue
state UP group default qlen 1000
link/ether 0e:7f:c3:fb:25:b1 brd ff:ff:ff:ff:ff:ff link-netnsid 0
inet 192.168.1.94/24 brd 192.168.1.255 scope global host0
valid_lft forever preferred_lft forever
inet6 fe80::c7f:c3ff:fefb:25b1/64 scope link
valid_lft forever preferred_lft forever
--------------------------------------------------------------------

There is a public IP with a domain name (http works OK).

I entered this line in pg_hab.conf:
------------------------------
host mattermost mmuser 127.0.0.1 md5
--------------------------------------------------------

Now when testing:
--------------------------------------
% psql --host=127.0.0.1 --dbname=mattermost --username=mmuser --password
Password for user mmuser:
psql: FATAL: no pg_hba.conf entry for host "127.0.0.1", user
"mmuser", database "mattermost", SSL off
------------------------------------

What am I doing wrong?

Thank you for help
