Again errors when trying to login

Hello,

It started again to give errors when trying to log in, like last week.

Warning: pg_connect() [function.pg-connect]: Unable to connect to PostgreSQL server: could not connect to server: Connection timed out Is the server running on host "plato2" (198.204.241.82) and accepting TCP/IP connections on port 5432? in /usr/local/apache2/htdocs/gixen/database.php on line 17

Hope it will be fixed soon! Thank you in advance Mario!

And after a while it gives this error like last week, the password and username are correct:

Warning: pg_connect() [function.pg-connect]: Unable to connect to PostgreSQL server: could not connect to server: Connection timed out Is the server running on host "plato2" (198.204.241.82) and accepting TCP/IP connections on port 5432? in /usr/local/apache2/htdocs/gixen/database.php on line 17
