opret forbindelse til online MySQL db

Kan ikke oprette forbindelse til min server på nettet, har kun haft held med at gøre det på localhost.. har følgende kode:

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;


public class Main {

    public static void main(String[] args) throws Exception
    {

        Class.forName("com.mysql.jdbc.Driver");
        Connection con = DriverManager.getConnection("jdbc:mysql://DATABASENAVN","BRUGER","PASS");
       
        int id = 1;
       
        PreparedStatement statement = con.prepareStatement("select * from users where id = '"+id+"'");
        ResultSet result = statement.executeQuery();
       
        while(result.next()) {
            System.out.println(result.getString(1) + " " + result.getString(2));
        }
       
       
    }
}



får følgende fejl:

Exception in thread "main" com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
