No water thru door. My water stopped comming out thru the dispenser. I disconnected the water line

Question

My water stopped comming out thru the dispenser. I disconnected the water line at the bottom of the freezer door and when I push the water button the water will come out of the dissconnected tube. The problem is some where between the bottom of the freezer door and the water despenser. Any idea on how to fix? Thanks for your time,Brian
