Is it glazed? Sounds like it might need toeing and heeling. If the top of the door is leaning outwards it has ‘dropped’ meaning it’s no longer square. There are glazing packers between the glass and the door - at the bottom corner on the lock side and the top corner on the hinge side. These may need adjusting to re-square up the door. To get to them you need to pull the beading from the inside side of the door. Plenty of guides online to walk you through the process.
