Trampa problem, power supply

Hello, I have a question, I have a tramp board and I have a problem: I have a PCB box 21700 and I have a problem with the fact that I cannot turn off the skateboard with the power button, I have 2 x VESC 6 mkV, 100% work, they light up in blue, but the button does not respond, the button is also turned off 100% functional, the cube itself and the cables that go to the PCB are probably also functional since the button is functional, I am wondering about the faulty COMM cable, but I don’t know if it is faulty. I have the VESC TOOL application, when I set engines etc. the transmission goes to the PCB via Bluetooth and then goes further via COMM or CAN-BUS? Have you had such a problem??
