MQTT manual alarm

Hi

I use the MQTT manual alarm panel, today when I did try to arm the alarm from my phone and computer i get this error in my homeassistant log:

[homeassistant.components.alarm_control_panel.manual_mqtt] Invalid code given for armed_home

But im 100% sure that i use the correct code given in alarm.yaml, i did also tro to change the code and reboot HA, still same problem.

What could be wrong?
