RDS connected resource to EC2 is deleted automatically after few days

0

I have RDS db that I connect to EC2 instance so that the EC2 instance will can connect to this DB. The problem is that after few days the connection is deleted automatically and I need to re-create it again and again. What can be the reason of this behavior?

Hello.

What exactly happens when a connection disappears?
Does this mean that the security group settings are automatically changed?
Or does that mean RDS will disappear?

    thank you for your reply.
    Are you following the conditions listed in this document? https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/ec2-rds-connect.html#ec2-rds-connect-viewing

    • The name of the security group associated with the compute resource matches the pattern ec2-rds-n (where n is a number).
    • The security group associated with the compute resource has an outbound rule with the port range set to the port that the RDS database uses.
    • The security group associated with the compute resource has an outbound rule with the source set to a security group associated with the RDS database.
    • The name of the security group associated with the RDS database matches the pattern rds-ec2-n (where n is a number).
    • The security group associated with the RDS database has an inbound rule with the port range set to the port that the RDS database uses.
    • The security group associated with the RDS database has an inbound rule with the source set to a security group associated with the compute resource.
