Keep getting error from wifikeyboard app

[buggyboy]

Hi,
wifikeyboard works, http://localhost:7777/ works too, but DesktopKeyboard2Android keeps displaying on each keypress :
unexpected response from android Wifikeyboard app [multi].
I first tought I had a problem with WKB having a page open and connected while running DK2A, but I still get the same problem after a reboot of my pc. WKB runs on a Nvidia Shield Pro. DK2A, on Win10
