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
Try to connect from the mysql command line (http://dev.mysql.com/doc/refman/5.1/en/mysql.html) and see what's this utility returns you. I found it's easier to debug that way.
mysql -hMY-DB.us-east-1.rds.amazonaws.com -uMASTER-USER -pPASSWORD
If that's doesn't work, it means your amazon RDS security aren't configured correctly. (which is the common problem).
