psql client not connecting and not giving any feedback.

You might check that you have network access from your terminal to the RDS resource. You can install this handy utility to determine if you can access your RDS database from your terminal

./paping <REMOTE HOST> -p <PORT>

Hi,

If I assume the database is not production yet, s

And if you want to access from your EC2 terminal, you can try to setup your database to be connected from EC2 easily by clicking this option "Connect to an EC2 compute resource" under "connectivity"

.

If you want to connect from your local computer:

a. Without VPN:

• set RDS public accessible to "Yes"
• set security group to allow inbound traffic from your local public IP address

But highly recommended you setup client-vpn, software-base vpn such OpenVPN , so you can put your databse still in private network which more secure then put it on public subnet.
