Homekit bridge, Devices do not respond?

Hi there,

I have a problem using the homekit-bridge-integration.
The last weeks it works perfect and now suddenly, the devices do not respond any more.
I also replaced my old FritzBox with a Unifi Cloud Gateway Ultra (behind my glasfiber-NAT). But after the change, HomeKit worked fine.

I also updated Home Assistant to latest 12.5. But doesn’t help.
Before it was 12.1 or 12.2 - with that version it worked initial. I can’t comprehend, why it stopped working.

IPv6 has been enabled in the unifi-gateway. Hopefully I did it right and this isn’t the problem…

What can I do? Is there some debug-option to find the error?

Kind regards!

EDIT:
I tested to use some Voice Commands on the AppleTV remote. Like „Light xy 60%“ and it worked! So it seems like, the AppleTV is connected to the HomekitBridge of HomeAssistant.
But the iPhones are not?

Ok, it works.
I just “refresh” the bridge in home assistant (over the pencil-icon) and now everything is achievable from the iPhone.
