Having Issues Connecting

[r-joyce]

I am trying to get our application connected to a Stardog cluster using Stardog Graviton up in AWS. I have a VPC that contains two subnets, a public one for our internet-facing services and a private one for our backend. The application that needs a Stardog cluster is within the private subnet. Here's what I have done so far.

• Created a VPC Peering connection from our VPC to the one that Graviton generates.
• Updated the route tables to forward IP requests within the private subnet for the 10.0.0.0/16 CIDR block range (the CIDR block of the Stardog clusters VPC) and set the target destination to the peering connection ID.
• Updated the security group that was generated to also allow ports 22 and 5821 from our VPC CIDR block range.

In addition, I also allowed all ICMP traffic from our VPC CIDR block so that I could ping specific instances. Our VPC is using the 172.16.x.x CIDR range so I know it's not an IP conflicting issue. The goal is to lock this down as much as possible and not utilize the internet-facing load balancer at all.

I am unable to ping any of the instances within the generated VPC and am unable to connect to the cluster from neither our application or Stardog studio - pointing to either of the load balancers or even instances directly. Any idea as to what the issue might be?
