[RN'd 2.2] Error adding node via it's external IP

2.2.0 - Build 814

Usually I am able to add a node via any valid IP address and upon add, it will identify itself as the correct IP.

In Amazon, this frequently comes up when adding a new node via it's external IP, and then it joins the cluster on its internal IP.

On the recent build, this is not working and I am getting:
Prepare join failed. Could not listen on address "54.241.121.223": eaddrnotavail" (this is from "Add Server" in the server nodes)

I've reproduced this twice and double checked that adding the node via its internal address worked fine. I also confirmed that the couchbase UI is available via the external IP.

Logs from orchestrator and node being added are:
