KNX OpenHab Binding - Device not recognised

Dear community!

can someone help me with configuring the KNX binding?

I ran into following problem in the PaperUI when trying to connect one KNX device:

KNX IP Gateway works fine - shows to be online

KNX Device Parameters:
Bridge selection: KNX/IP Gateway
Address: 0.0.1

Channel: Switch
Address: 0/0/1

Kind regards,

Do you have access to your KNX project (ETS)? Are these PA addresses valid, GA’s also?
Are you sure you are trying to communicate with devices on the KNX backbone?
