openHABian and Homematic Binding - Connection refused

Hallo,

i have installed openHABian 3.4.2 via image file and Homegear via openhabian-config.

The thing Homematic Bridge of the Homematic Binding is Offline and has the COMMUNICATION_ERROR java.util.concurrent.ExecutionException: java.net.ConnectException: Connection refused.

If you use the latest Raspberry Pi OS (Raspbian) instead of openHABian and install openHAB manually first and then homegear (stable), then the connection to the Homematic Bridge works.

Does anyone have an idea why this doesn’t work with the openHABian installation and Homegear?

I have a HomeMatic Wireless Module for Raspberry Pi (HM-MOD-RPI-PCB) plugged into my Raspberry Pi. But i think that doesn’t matter for this problem.

Greetings Rudi

I do have the same issue. Anything you did find out to resolve this?
