Please try scanning the device again, and use the -sV option to see if
you get a service fingerprint. If so, then submit it at

Does this service always run on port 31727, or can it be different? If
it can be different, we're better off with a service fingerprint.
I guess the service name would be "diagd". Do you know anything else
about the service?
