Physics2D.Raycast not working, why?

Question

Unity

In general, the code that worked properly stopped working, I can’t figure out what’s wrong. hit2Dir always has a value, hit2.point = (0,0), and with hit2.collider.name an error occurs (because the raycast does not hit anywhere, although there is an object above it), when hit3 always works. What could be the problem?

Code

hit2 = Physics2D.Raycast(posOfHit, hit2Dir, maskGround);
            print("hit2.point: " + hit2.point /*+ "hit2.collider: " + hit2.collider.name*/);
            hit3 = Physics2D.Raycast(posOfHit, hit2Dir * -1, maskGround);
            print("hit3.point: " + hit3.point + "hit3.collider: " + hit3.collider.name);
