Openhab 3 / homematic binding / CCU (raspberryMatic) not connection / Jetty start failed

Hello I am running OH 3.0.1 on 1 server and raspberryMatic on server 2.
The target is to import the homematic devices in openhab

openhab server: IP 192.168.178.70

here is the routing table:
root@openHABianDevice:~# route -n
Kernel IP routing table

raspberrymatic: 192.168.178.50

Binding: homematic

Openhab find the bridge and the device, but it is running into problems and then a communication error comes up.
