Apple Homekit not connects

Hi Guys,

I tried to connect my OH to Apple Home App on my wife’s iphone but it does not works.
I tried it base don the description using the QR code

My OH4.2.2 runs on RPi4, iPhone is on IOS18.3
I instelled Homkit a long time ago but never paired with ny Apple account.
Already removed the Homekit App from OH and reinstalled, OH restarted cache cleared,

The phone says that Ethernet connection should be btw the router and device. Is this true?
ALso tried to connet to my suns iphone but no success.

Or any other idea?

Thnaks a lot

Sorry forgot to update my ip address…
