Homekit will not pair

Hi All,

I am new and try to connect OpenHAB running on my Synology diskstation with homekit.
It is configured and I can see the OpenHAB in Homekit. But I am not able to pair. I’ve searched this forum allready and tried many solutions, but none of them are working for me.

I’ve used the PIN: 031-45-135 or 154 and set the ip address of the network interface the same as the ip from the Synology where it is running on. Is this correct?
I did not set any items in the item folder this time. Yesterday I’ve tried it with item settings but also no succes.

What can I do to get it working?
