Wiser for KNX app registration

[Novodk]

I can't create an account on the "Wiser for KNX" android app it says": Specified device has not been found on the network. You must be connected to the same network as the device for the registration. change Network and press ok, or cancel the registration." But if i click "Local Control (home network)" and type in the local IP address it works. I know about the 5 minuets after reboot, but that doesn't work either.

Any suggestions?
