MQTT activation button don't work in Nuki App

Hello, after last Home Assistant updates Nuki integration don’t connect my lock trough Nuki Bridge. So I want to activate MQTT. I have mosquitto broker for MQTT and use it to connect zigbee devices with zigbee2mqtt.
When I open Nuki app and go to Settings>Smart Home> MQTT I want to click Activate button but nothing happen.

I have smartphone OnePlus9pro with android 14. I try to change theme to light.
Regards.

I have the same problem, I assume that you are not connected to the Thread network “correctly”. You need to enable NAT64, which is my case, is not possible with a Google Home Hub.

I don’t know I need thread network to use MQTT.
