PostgreSQL – Cannot Connect with a Created Role

I am using PostgreSQL 11.3 on Fedora 30. With the postgres user, I can use psql or connect to the cluster in PgAdmin 4, but when I create another user, for example :

CREATE ROLE myuser LOGIN PASSWORD '…';

I always get an error like :

FATAL: password authentication failed for user "myuser"

I had a look at other similar questions here (including this one, but I don't have a case folding problem), and I still cannot make it work.

Here is my pg_hba.conf file :

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     scram-sha-256
# IPv4 local connections:
host    all             all             127.0.0.1/32            scram-sha-256
# IPv6 local connections:
host    all             all             ::1/128                 scram-sha-256
# Allow replication connections from localhost, by a user with the
# replication privilege.
local   replication     all                                     scram-sha-256
host    replication     all             127.0.0.1/32            scram-sha-256
host    replication     all             ::1/128                 scram-sha-256

What I am doing wrong? Thank you for any help
