I'm following the directions on the https://github.com/bosnet/isaac-consensus-protocol/blob/master/README.md, and it doesn't say to setup localhost:54320 so when I try to send message it fails. If I change the command to a node which is already running i.e. localhost:5002 it passes. I would suggest it's explained in the readme to use http://localhost:port of a running node like localhost:5002, and change the commands to reflect working ports.
