Issues communicating across hosts

I have the current host setup

host1

  • testproject

host2

  • consul.discovery

When I ping consul.discovery from testproject, I can ping the ip and communicates, but cannot curl against it, however if I moved testproject to host2, it can work fine

they are both in AWS, same VPC, same security groups (opens all traffic locally)

Any ideas?

– tried verifying port open, here is result from nmap
bash-4.3# nmap -p 8500 consul.discovery

Starting Nmap 7.40 ( https://nmap.org ) at 2017-07-13 17:26 UTC

Looks like one of the hosts was using a public ip and other was private, once i readded both with private ip, it works now
