KMtronic stops working

[gomsoo]

Hi

I have 3 KMtronic with LAN, all connected to Domoticz.

Sometimes, when I wand to toggle in Domoticz, I got an error "Error sending command".
Reboot of the device doesn't help, but reboot of domoticz.

Why does this no longer work after a certain time and I have to restart the Domoticz service again and again?

When I create a Dummy Switch with an action, eg. http://192.168.1.38/FF0401, that still works, but not via the interface, which is provides by Domoticz

Debian 11.7
Domoticz: Version: 2024.1 (build 15805)
