That nothing is listening on that IP and port. This usually means any of the following:
- The hyperbox server is not running
- Your firewall might block the connection
- You installed the server somewhere else and you'll need to find the IP/Hostname to that machine
Note that support for the hyperbox server on Windows machine is poor. The hyperbox use-case is very much a Linux host as Windows adds a lot of problematic layers where you might not be able to actually manage your VMs.
