“Unsupported URL” when trying to connect

Hi,
I have Kodi 17.0 Beta6 installed on my QNAP, and i have no problem using “Sybu Kodi” for iPhone, but i get an “Unsupported URL” error when trying to connect with Kodi Remote.
The “Find Kodi” worked correctly btw.

* Latest IOS, latest Kodi Remote

Any ideas?
