Localhost Page cannot be found?

I’ve built the LearnNow App as I take the Rapid Developer Learning Path on the academy. After I configured the security settings, whenever I log-in, the homepage won’t show up and will always turn to this (see image below). Did I miss something? On setting the homepage perhaps? But when i click  “View”  again on the studio pro,  it’ll display the homepage right away with no problem. The page cannot be found issue is only after the log-in.

Did your button changed from 'run locally'  to 'run'?

I think you are running it in the cloud….
