Root: KNX/IP gateway did not respond to connect request

I can’t seem to connect to my KNX installation. I’m sure it’s a silly problem, but I can’t find it. (Yess I’m a newbee)

I have ETS3 professionial software on my laptop (connected through WIFI). Using this I can connect to my installation directly and give commands.
I have Home assistant running on Raspberry PI
I’m using a Weinzierl 730 to have a IP connection (192.168.1.2) to my KNX installation.
I can ping from my raspberry pi to the IP address of the Weinzierl

but when I restart my Home Assistant I always get the same error

The following errors have been logged this session:

17-01-08 11:07:18 root: KNX/IP gateway did not respond to connect request
17-01-08 11:07:18 homeassistant.bootstrap: component knx failed to initialize

17-01-08 11:07:20 homeassistant.bootstrap: Unable to prepare setup for platform switch.knx because dependency knx could not be initialized

This is the entry in my configuration.yaml
knx:
host: 192.168.1.2
port: 3617
switch:

  • platform: knx
    name: KNX Switch
    address: 0/0/1
    state_address: 0/0/3

Something I forgot?

Thx
