Raycast goes through

I don't know where is the problem, ray just goes through the wall. Layermask is checked correctly and origin is behind the wall. But it still goes through the cube. I want enemy AI not to shoot if there is a wall. Code:

   public virtual bool SeeingAlligned()
         {
             if (seeingOrigin != null)
             {
                 Ray ray = new Ray(seeingOrigin.position, seeingOrigin.forward*attackDistance);
                 Debug.DrawRay(seeingOrigin.position, seeingOrigin.forward*attackDistance, Color.blue, 2f);
                 return Physics.Raycast(ray, out hit, attackDistance, playerLayermask);
             }
             else
             {
                 Debug.Log("No ray origin for line of sight check");
                 return false;
             }
         }
