An NPC who walks to the nearest point to the player if he has not found a way to him

I’m trying to set up my NPC to walk up to the player, but what if the player is higher up and the NPC can’t get there because the waypoints aren’t given. Is there any way to check the place below for the departure of the free position of not the player, but below him relative to where he stands now?

My thoughts:
Perhaps it’s worth doing several pathfinding along the Y vector, counting down 5 at a time and choosing the nearest one?
