Connecting to Postgresql on EC2 Instance

Hi, I am trying to connect to a database "user" on a PostgresQL I set up on an EC2 instance. I believe I have allowed port 5432 on the inbound rules and I have modified the two config files. But I received this error message. Unable to establish connection: Connection to refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections. Would you please help me?

Hi, The "*Connection to refused*" error would have occurred when the Virtual DataPort server is unable to reach the PostgreSQL in the EC2 instance. In order to resolve the issue, I would perform the following checks: * Check whether the server you’re connected to has started and running. * Check if you have a firewall that is blocking the port that you are trying to listen to. Additionally, in order to get more information about this error, I would check the **vdp.log** file which is located under the folder “**<DENODO_HOME>/logs**” Hope this helps!

Thanks! We figured it out. It was one of the config files need to open to all rather than localhost.
