Cannot pair HomeKit bridge with iPhone

Hi, I have a raspberry pi 3b running HassOS connected by Ethernet cable.

My iPhone is connected via wifi, either through a Tenda nova mesh wifi system or directly to my BT home hub.

I have installed the HomeKit bridge integration. It generates a QR code to add into home app on iPhone. But never pairs. Have tried a lot of different lines in the configuration file. Demo mode, including entities, excluding all. Etc. It will not pair, I have tried different iPhone connected to different wifi networks. Other HomeKit devices have shown up automatically but I want to expose my zigbee devices and tuya devices to home kit.

same issue… it was working but suddenly it was gone… used Alexa most of time and since today needed using Homekit, not connected… start over and now stuck with same problem
