HDRI Skysphere Reflections

Hi all. I just started working with HDRIs as skyspheres and I ve been having some problems. Would greatly appreciate if you can help.

I started with this tutorial: and got it to work.

I just cannot manage getting any reflections(from the HDRI skysphere) on a reflective mesh.

Example bellow you can notice that on the edge around the sphere there are reflections but on the main part of it is black. Material Params: Metalic: 0 and Roughness: 0
