Error connecting to PostgreSQL

rainyskilI

I'm using the correct data, but my script produces this:
sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) connection to server at "pgsql4.serv00.com" (213.189.52.181), port 5432 failed: Connection timed out
Is the server running on that host and accepting TCP/IP connections?
How should I fix this?
