shadow not working

hello there!
i use the free version of unity and i wanted to give my game some shadows so i got a directional light and set it to “hard shadows”,but i don’t see any shadows.
what do i need to do?

###Shadow Checklist

1. Enable shadows in Edit > Project Settings > Quality.

2. Ensure all models cast and receive shadows correctly

3. Check to make sure your light is set to realtime, is directional, and does indeed have shadows enabled

4. Make sure you are close enough to the shadowed surface to see the shadow (you can adjust shadow distance in quality settings)

Let me know if this helps =)

Thank you for helping. I think I figured out what the problem is, for some reson objects will cast shadows without my textures, but when I apply textures the objects won’t cast any shadows. What do you think is the problem?
