Homematic and OpenHab 1.8 not Working

Hello Community

I’ve got my homematic ccu2 and want to add it to my openhab installation. I’m running openhab 1.8.2 with the homematic binding in the same version. The CCU2 is at 2.17.15.
But the binding can not start:

Can anybody help with this issue?

Kind regards
and a happy easter

//edit
I’m running openhab on a raspi2 wich uses a bridge interface.
A TCPDUMP didn’t show any traffic between openhab/raspi and the ccu2.
Anybody experiance with this kind of setup?

Can u post your config?
did you try to use ip of ccu2 instead of homematic-ccu2.fritz.box?

Do you mean the homematic part of openhab.cfg

############################### Homematic Binding #####################################
homematic:host=http://homematic-ccu2.fritz.box
# homematic:callback.host=
# homematic:callback.port=
# homematic:alive.interval=
# homematic:reconnect.interval=

I have changed my network config back to an eth interface without success.
Useing the IP adress did not change anything.
Because my raspi has many IP Adresses, I have also tried to use the callback host with name and IP without success.

OK, I got the issue.
Tried to connect to my ccu with an address which started with http://
After removing the http:// it is now working fine. It was a a special kind of stupidity…

homematic:host=homematic-ccu2

Problem solved an thread can be closed
