Bar is too high on your back. Reach your hand over your opposite shoulder (right hand over left shoulder or left hand over right shoulder - doesn't matter) and feel for the bony protrusion. That's the spine of the scapula and the bar should sit just below that. The bar should be in the heel of your hand with a straight wrist. Stop rolling your knuckles over the bar.
