Looks like you engine has already one host with an IP address which is the same on your second node.
Looking at your setup console above, I see:

The Host ID is already known. Is this a re-deployment on an additional host that was previously set up (Yes, No)[Yes]?

Did you remove the host with id2 from the engine before trying to re-deploy it using (probably) the same IP address?
