I have a similar issue as DavidJ (post #36). I have gone through the step-by-step instructions and installed the various elements on HA running on a Raspberry Pi 5 (Yellow). I have run into the following Operation Timed Out problem (it continues to try to connect but never does). I am using port 1002 which is set to 0 for the time-out. It shows idle in Comfort Server Manager. I am able to connect with no problems to my system using the UCM/ETH03 (firmware v2.23) on port 1001 from Comfigurator.
I am at a loss as to why it refuses to connect.
Here is the log file:
