Shading/Normal problem

Fantasma

 I am making a shipping container and on the doors there is a shading or normal problem, I checked the number of edges for each face and they're all 4 edges, any suggestion?

Hard vs soft edges. On those sort of angle changes, you'd want to put a hard edge, so it doesn't try to average the normals/tangents at those extreme amounts.

Or try face weighted normals.

I think I tried playing with the other bevel settings but never knew exactly how it worked, thank you
