Elastic Beanstalk and RDS MySQL connection timeout

Have you setup the inbound rules correctly. From my experience, once you set the inbound rules, there should be no issues. For information about setting up security group inbound rules, see https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Overview.RDSSecurityGroups.html .

So I need to create a specific MYSQL/Aurora inbound security group type for EB -> RDS?

Correct - its best practice to set the inbound rules so the IP of your Elastic Beanstalk instance is allowed to interact with the RDS instance. We cover that point in the AWS Tutorial that talks about creating a Java web app that interacts with RDS. See: https://github.com/awsdocs/aws-doc-sdk-examples/tree/master/javav2/usecases/Creating_rds_item_tracker .

See the section under Set up the RDS instance. I had this app deployed on AWS Elastic Beanstalk and once the inbound rules were setup, i never had database connectivity issues.
