Change Frontpage to Profile URI - 404

Hi all,

I tried to create my own personal website using open scholar. To do that, I changed the front page with drush to the profiles url. However, I get a 404. The page can be loaded when entering the URL directly though. I can't set the frontage through the site-information. I wonder how that happens. In the database, it is registered correctly. Am I missing something?
