KC828-Server unable to respond mqtt command until restart

[Jessica]

do you use INPUT for mqtt message?
here is a option in webpage: "SW trigger output" , you can set to "disable", so that INPUT will not trigger OUTPUT directly, then will send MQTT message when INPUT trigger.

Thanks for the response, SW trigger output does not solve the problem.

I found the bug, when I stop MQTT Broker on CM4, then KC868-Server side crashes somewhere and stops working, even http service on KC868-Server doesn't working, except ping.

But how to restart KC868-Server service? I don't like to power-off then power-on again to run it.
