[SOLVED] Newbee: cannot get CCU3 with Openhab 2.4.0-1 working

Hi,

today I got my CCU3 and I wanted to get it connected to my OpenHAB 2 (2.4.0-1).
OpenHAB is running on my RaspPI 3B+.

Homematic binding is installed. Under things I see:

OFFLINE - COMMUNICATION_ERROR java.net.SocketTimeoutException: Connect Timeout

openHAB tail shows:

2018-12-19 21:48:57.921 [hingStatusInfoChangedEvent] - ‘homematic:bridge:xxxxyyyyzzzz’ changed from OFFLINE (COMMUNICATION_ERROR): java.net.SocketTimeoutException: Connect Timeout to OFFLINE (COMMUNICATION_ERROR): Total timeout 15000 ms elapsed

2018-12-19 21:49:52.980 [hingStatusInfoChangedEvent] - ‘homematic:bridge:xxxxyyyyzzzz’ changed from OFFLINE (COMMUNICATION_ERROR): Total timeout 15000 ms elapsed to OFFLINE (COMMUNICATION_ERROR): java.net.SocketTimeoutException: Connect Timeout

What I am missing?

Thanks for any help…

After writing this topic I found it by myself.

I had to put my openHABian’s IP address into the CCU3 firewall settings inside the section ‘IP adresses for limited access’.

Then I restarted openHAB and now CCU3 is online.
