The error code 08001 is a generic error code telling that the JDBC driver could not connect to the database. The reason for this could be many.
You should enter the IP address or DNS name of the server where the database runs as the Database Server and the Database Port it listens to for TCP/IP connections, by default 5432.
After you have entered this, please use the Ping Server button to see if you can reach that server and port. If you get an error message, you have either entered incorrect Database Server or Port values, there is a firewall that blocks the connection, or the PostgreSQL server is not configured to access connections from your PC. If Ping Server says everything is fine but you still cannot connect, the problem is most likely with the login credentials for the user account you specify.
I hope this helps,
