I was trying out the demo for single page app. Installed it and opened localhost:3000. A nice Javascript Sample Project appeared but after Login (that is succesful) I always get an unauthorized message in the user history. Also the state of the login button does not change.

Hi @philimmo,

Welcome to the Auth0 Community!

I have looked at your tenant logs and found the “Unauthorized” error. However, to investigate this issue further, could you please [capture the login events in a HAR file](https://auth0.com/docs/troubleshoot/troubleshooting-tools/generate-and-analyze-har-files) and send them to me as in a private message?

This will help me trace the origin of the issue.

Thanks,  
Rueben
