Nose strut collapsed while braking hard on landing.

Last time this happened I came to my hangar to find my nose strut was fully compressed and hydraulic fluid puddled around the tire. It was a bad seal and got fixed. Yesterday I landed like normal, then went on the brakes a little hard to make the taxiway. The nose sank and now is completely collapsed. It will not stay up if I lift it either. Nitrogen? Bad seal? Bad strut? Looking for ideas. Anyone encountered this before?
