Player passing through confine

hello, I try to make confine in my platform 2D game.

I follow this tutorial:
https://blogs.unity3d.com/2018/07/17/cinemachine-for-2d-tips-and-tricks/

I used edge instead of box collider, but my player forcing the confine and go out.

How can I fix it?
I am so confused that I have no idea what info or image I have to share in this post.

Thanks.

 

I solved using edge radius
