Cannot add HomeKit Component to Home App

Hi! I’m having issues with the HomeKit component. I have installed the component in Home Assistant and can see in the logs that it works (the states of my switches and lights are updated as expected). I also get the card with the HomeKit pincode in the Home Assistant UI.

The problem is that nothing happens when I try to add HomeKit to my Home App. After I have inserted the pincode I get a never ending spinning wheel…

I am running Home Assistant v70 using python virtualenv on Ubuntu 16.04, which is running in a VirtualBox environment on a MacMini. I have forwarded port 51827 in VirtualBox, but I can’t see anything bonjour-related when I run Bonjour Browser in MacOS or the Discovery App in iOS.

Any idea where I should begin debugging? Since the component seem to work in Home Assistant I suspect that VirtualBox is blocking the bonjour traffic somehow?

That might help: https://github.com/home-assistant/home-assistant/issues/14567
