The issue appears to be due to an incorrect link to the profile page. I am facing the same issue.
I noticed this under my Activity Stream https://activities.sap.com/ for my profile.
It takes me to http://scn.sap.com/profile/reagan.benjamin where as it should be
http://scn.sap.com/people/reagan.benjamin or https://people.sap.com/reagan.benjamin The "profile" in the first link is invalid. When I click on my profile I get this error under my activities stream.
I believe the link should be the one that points to people.sap.com when we click on a profile instead of the one that takes you to SCN.
The profile URL that is getting populated is not correct. This happens for other users as well. I could see for some users the profile link starts with scn.sap and for some it starts with people.sap
