I run my test program with 2 ways in the same login environment.One succeed and one fail.

The different is connection options(Unix Domain Sockets/TCP Sockets).

is your server listen_addresses = '*' ? if not, its not listening on the interface that will respond to connections to 'HOSTNAME'

and, is pg_hba.conf configured for an appropriate authentication method for `host` connections ?
