Registration of this item is not allowed: Error 400

I use Portal for ArcGIS and the GIS server is federated to it.

I'm trying to register an item on my organization's Portal for ArcGIS. I followed a guide to run Web AppBuilder 

(Developer Edition) from this link: Get started—ArcGIS Web AppBuilder (Developer Edition) | ArcGIS for Developers

I've been stuck on the part where I should register the added item (web appbuilder) and get App ID so I could run the Web AppBuilder (which I downloaded and run from the script) in the browser.

I tried two methods to register the item, no avail. I tried the guide from this link Bug: Register option is not available on the Item Details page for apps in the Portal for ArcGIS hom... 

When I click "Register" in the REST API dialog, I always get the "Registration of this item is not allowed: Error 400".

What am I doing wrong?

Thanks for any advice
