Invalid redirect error after "confirm_access"


Invalid redirect error after "confirm_access"



I am experiencing some problems with OAuth v2 in my ASP.Net application. After sending request to https://oauth2.constantcontact.com/oauth2/oauth/siteowner/authorize?response_type=code&client_id={my... I have been redirect to login page then confirm_access page. After I click "grant access" button, the "invalid redirect" error occurs.


I also tried the sample C# app and same error happened there too.


I have searched on forum however nothing comes cross my issue. Can you please help me troubleshooting?


Thank you!
