Yep tried that. Stopped and started the application and still doesn't work. Anything I should do after editing the hosts file? It is behind a load balancer. 

Hmm not sure, I would double check that it was done correctly. All occurances of this problem that I can find all come back to the same fix.

I expect that your loadbalancer is in front of the application as a proxy, not as an outbound proxy? If yes, it shouldn't matter.

Can you get any logs from the Amazon side of the connection information?

Ah, okay I realized that my hostname on the EC2 instance was 

ip-10-0-X-X so I had to update my hosts file with the public IP, the cname, and then that hostname.

Works now. Thanks.
