Please:
1 Check that mysql is running on server <SERVER>
2 Check that mysql is running on port <PORT> (note: 3306 is the default, but this can be changed)
3 Check the <MYSQL_USER> has rights to connect to <SERVER> from your address (mysql rights define what clients can connect to the server and from which machines) 
4 Make sure you are both providing a password if needed and using the correct password for <SERVER> connecting from the host address you're connecting from
