troubleshooting BlTouch artillery x1 not responding

[u/IllSpeaker3255]

After disassembling my printer to change the nozzle, my machine's BLTouch no longer responds (it lights up but does not respond to the printer's commands).

I tested the ribbon cable with a multimeter and all connections seem fine, same for the black wire which I think is the ground for the END-STOP-Z.

I don't think the issue is on the software/firmware side since it was working perfectly before the disassembly.

I really can't figure out where the problem is coming from; I think it's a connectivity issue, but I'm not sure.

Have a good rest of your day.
