Okta sign in error

I have downloaded sample code from below url and tried to log in but it is showing an error, could some one help to understand the error.
GitHub - okta/samples-aspnetcore: samples-aspnetcore

Thank you

Hi @ajith.joseph! Can you check Dev Tools and see if there are any errors in the console or network tab? You can also check your Okta Dashboard Reports > Sys logs for any related errors.
