In reply to Edo.

Hi Edo - it's hard to say what might be going on there but I believe it is specific to your environment or perhaps networking? I can tell you that without a doubt our application that was the basis of this user-scoped access example was running on a specific port and I registered that to SAS Logon in the `redirect_uri` field of the Client I created. User redirects to and from our app as I outlined them in this post worked as expected with our app running on a specific port.
