Postgres connection error

I have a database that I would like to connect through QuickSight. I asked my coworker to change the inbound/outbound rule so that the Postgres allows QuickSight to be connected. He used these two documents: Authorizing connections from Amazon QuickSight to Amazon RDS DB instances - Amazon QuickSight, Create a private connection from QuickSight to Redshift or RDS | AWS re:Post (repost.aws)
However, I’m still getting the issue of connection timeout error. Does anyone know how to solve this issue?

Hi,

Check these rules

  • Create or identify an IAM role associated with the Amazon Redshift cluster.
  • Add the IAM policies AmazonS3ReadOnlyAccessandAmazonAthenaFullAccess to the IAM role.
