ping network scan

just downloaded the latest community bixdata server and desktop client. easy to deploy, love the client interface, love the pop-up notifications, but I have a serious problem that I cannot understand.

I do a network scan of the whole /24 block that my servers are on, and It returns a list of ip addresses, even resolves the ones it can, but for some reason, it shows that almost all of my servers are offline, even though I know they are!! even from the same host machine, i can ping to any one of my servers without any packet loss and with a very low latency (as one would expect for machines on the same lan)

what up with it? am i missing something?
