If your nodes are deployed on an internal network, (e.g. a node deployed on any of the following: AWS private network, OpenStack tenant network, VMware NSX tenant/private network) you must specify **the internal IP of the node** as a parameter to the CLI.

If in doubt, run `ifconfig` on the node, then see what IP address gets reported and specify that IP. Your external IP will not get reported by `ifconfig` as that is configured external to the node.
