This has been killing me all day.
I've set up Elastic Beanstalk, working fine.
Set up RDS, working fine and can access from my laptop.
But when i try to connect to the RDS from my ES application i get a timeout error.
Extra info is that i'm using a Laravel application, connecting to a MYSQL database. All of my environment variables have been loaded and accepted fine.
I'm almost certain it's a security groups setting, but the docs are so tremendously bad for AWS that i haven't got a clue what to do!
Any help?
