Bake normals map does not work well I have issue woth baking normals. In some reason bake does not work well. I tried a lot of ways and configs.. But my normal map is incorect.

When I'm trying to use this generated normal map in Unite or Bldender for low model I see edge of low poly model. In some reason Ray distance does not work for case when low poly sticks out a little.

I'm using Blender 2.81.

Do you have any suggestions how to bake normal map without this issue.

See below screenshots:

High model inside in the low. I generated high model from low by smooth

Tring to use this normal
You should make your low poly model smooth shaded and add at least one bevel in this case. 

When blender bakes the normals, it ray casts from the low poly surface inwards along the interpolated normal until it hits the high poly (or not).

If you need the low poly to intersect with the high poly then you can make a copy of the low poly and scale (or shrink/fatten) it up and bake with that. It is also possible to use a Displace modifier to raise the surface a bit during the bake.
