Review 'host' lines in pg_hba.conf (SELECT * FROM pg_hba_file_rules WHERE type LIKE 'host%';). Test psql 'host=<server> user=postgres sslmode=disable' and sslmode=require locally and remotely: only intended encrypted, password-authenticated (scram-sha-256) logins may succeed.

Use hostssl lines with scram-sha-256 for required users/networks and hostnossl ... reject for the rest, e.g. hostssl all postgres 0.0.0.0/0 scram-sha-256 and hostnossl all postgres 0.0.0.0/0 reject, then SELECT pg_reload_conf();
