Why can I not connect to the panel using USB? Getting error message – Object reference is not set to an instance of an object “_”

Power cycle the panel leaving the USB cable plugged in (If there is a battery/UPS connected please disconnect it).
Ensure that the USB-Comport driver is properly installed within the used laptop/PC;
If the above has been confirmed then restart your computer
