Answer 1

Maybe a stupid question, but have you opened inbound Security Group rules?

This error is a result of the inbound connection rule set on your DB instance.

In AWS RDS console, under 'Databases', click on the 'DB Identifier' of your RDS instance. Then in the 'Security group rules' section, click on 'Inbound' type security group and edit the inbound rule to allow appropriate inbound connections.

IF you are trying to connect from an EC2 instance, then the Inbound connection can be the security group of your EC2 instance on port 3306.

See point 4 in the following link: Create a VPC security group for a private DB instance

If its not Security Group, then it could be a route table issue.
