I am currently using this KC868 server board with CM4 model with homeAssistant installed on it and for the 16 digital input and output as well as the binary sensors of this KC868 board I was using mqtt inorder to communicate with homeassistant. everything worked well. I was controlling several lights as well as using the digital inputs for door window sensors. But now all of a sudden the kcs firmware seems to be not responding. HomeAssistant is still working but the rest part of the board is not working.
This board shows IP too but when i ping to IP in browser in order to login, page doesn't load. keeps buffering.

how about re power on of KC868-Server? Do you have disconnect/connect ethernet cable? or you are using wifi of rest board?

I tried this as well but suprisingly nothing is shown in the UDP Scan tool. But IP detection tool like FING and Advanced IP scanner shows the IP of the board.

I am once again facing this same issue. Home Assistant running on CM4 model of this KC868 server board is working fine. Even the ESP32 present in this same board which i am using via esphome in homeassistant is working fine but time and again this board, mosfet outputs and the switches connected to toggle those mosfet outputs doesn't work. Seems like the Kincony Arm chip in this board failed. I tried re-power also. Re=powering sometimes works and sometimes doesn't. Not sure whats causing issue. I have been locked out from controlling my lights twice already due to this issue.
Please check regarding this issue
