Running AWS but 0% CPU usage

It sounds like this issue which is inherited from the upstream Bitcoin code

Internal IP's Connection Problem

I’ve filed Document that: Nodes behind the same public IP may not be able to connect independently · Issue #1416 · zcash/zcash · GitHub . This is an upstream Bitcoin issue (see Running bitcoind on >1 computer, same network , which suggests a port forwarding workaround). We probably will not be able to help further with this before launch.
