Can't connect to AWS RDS

Hi there, I hope you can help me.

I have launched a network connector on AWS through the OpenVPN Cloud panel and I'm not been able to access to my RDS resources with the VPN.

Checklist I've made:
  • Add the OVPN subnet (100.96.1.32/28) to the route table attached to the subnet
  • Disable source destination checking in the EC2 instance
  • Add inbound rule to my RDS security group to allow all traffic incoming from the security group attached to the EC2 instance created by the connector
  • EC2 and RDS belongs to same VPC and the same subnet
Background:
When I created my OpenVPN cloud account, first, to test the service, I launch an aws connector to a testing AWS account and it worked. I was able to connect only to my RDS instance using the VPN. Then I deleted the network and connector from the OVPN dashboard and I created a new one to connect to my real AWS account. Here is where I can make it work. The only real difference between my testing and real aws accounts are the db engines. In my testing account, I tested it with a MySQL db, in real account, my RDS instances are PGSQL. Since I didn't have to specify any port in my test, I think this is not the issue.

I would like to know if you can help me to figure out what's missing in my setup.

Many thanks,
Luis.

OpenVPN Cloud is not OpenVPN Access Server. Wrong place to ask questions.

Use https://openvpn.net/support for your OpenVPN Cloud questions.
