I have a site to site VPN connection from my on prem network to the VPC RDS resides in. I am trying to connect to mysql using the DNS endpoint RDS provides. I am unable to connect to the DNS endpoint but I am able to connect using the private ip that the endpoint resolves to.
I assume that the DNS is internal to AWS and my on prem network can not resolve it.
The RDS instance is publicly accessible.
How could I connect using the DNS endpoint?
