Issue with scope/authentication

I have tried to create a new post with both https://micropublish.net/new and https://quill.p3k.io/new but they seem to fail.

Both services could authenticate just fine.

Quill says:

Your endpoint did not return a Location header.
See Creating a Micropub Endpoint for more information.
