I can\'t get PHPMyAdmin to connect to my Amazon RDS instance. I\'ve granted permissions for my IP address to the DB Security Group which has access to this database I\'m tr
I had the same problem and nothing of the above solved it.
As it turned out the thing was in "Publicly Accessible" option of the RDS instance. When you create your instance this option is "no" by default and there is no place you can change it.
However, after creating the RDS instance you can make its snapshot, then delete the instance and then launch the snapshot. In launch options just set "Publicly Accessible" to "yes" and your phpMyAdmin will finally see you RDS MySql server.
Beware that DNS of the original RDS instance and the snaphot are different so you would have to change your 'host' in config.inc.php
