We believe that the device's port may have slightly sagged during use due to external force or other reasons, causing misalignment and preventing proper connection of Oculink cables. We recommend that you unscrew the motherboard screws to readjust the position, and then carefully adjust the Oculink interface to ensure the cable connector is aligned flush.
Removing the screws ensures that the Oculink interface on the motherboard is aligned with our port. Once your port can connect the Oculink cable, tighten the screws.
