I have following setup on AWS
- One RDS instance in Region 1.
- One Ec2 instance in Region 2.
- EC2-Security Group sgrg2 in Region 2.
I am trying to access RDS from EC2 by adding Security Group to RDS instance list. It is not authorizing.
Moreover, while adding sgrg2 to RDS security group, it is saying ' EC2 security group sgrg2 for account xxx does not exist'.
Please help.
