Can't find homekit - Ubuntu Docker setup

unfortunately I can’t share my devices with my new hass.io via HomeKit.

I implemented HomeKit with the change “homekit:” in the configuration file.

The HomeKit code now also appears in the notifications, but my iphone does not find Home-assistant.

I already did a lot of research, the Docker Container is set to host. DNS was set, unfortunately everything was unsuccessful.

so what could be the reason?

thanks a lot
