Did you correctly upgrade your whole environment to scram-sha-256?
<quote> To upgrade an existing installation from md5 to scram-sha-256, after having ensured that all client libraries in use are new enough to support SCRAM, set password_encryption = 'scram-sha-256' in postgresql.conf, make all users set new passwords, and change the authentication method specifications in pg_hba.conf to scram-sha-256.

The log says:
> FATAL: password authentication failed for user "centos" > DETAIL: Connection matched pg_hba.conf line 88: "host user password 0.0.0.0/0 scram-sha-256"
I can't understand where is the problem as both psql and pgadmin connect without problems using the same password

I don't believe that.
This is how it looks by default:
# Allow replication connections from localhost, by a user with the # replication privilege. local replication all trust host replication all 127.0.0.1/32 trust host replication all ::1/128 trust
