First thing is to make sure both DC-in MOSFETs are not shorted.OpenBoardView — https://github.com/OpenBoardView/OpenBoardView

If first DC-in MOSFET is fully shorted, both gates will have DC-in voltage on them, second MOSFET will never be turned on.OpenBoardView — https://github.com/OpenBoardView/OpenBoardView
