Ball velocity when detaching (throw)

Hello. I have line trace which shows correct start and end line and when im trying to set velocity to ball before detaching it, its thrown in different direction (no pattern). So Basically everything works except direction. Could someone explain me how to correctly set it?

Thank you

EDIT: The ball should be fired from hand to center of screen. Camera has offset to right side (60).

fixed…

follow gamera → get forward vector → * 15000 + follow camera → get world location and then + vector and plug to set vector
