问题
I have followed all the steps form the tutorial, but can't start the example. As I start the server and go to localhost:8080/playground2/ I enter all the fields, then it redirects me to a page where I log in with my admin account and the when I go to localhost:9443/oauth2/authorize it gives me an exception
when I check the server console, this is the error I see

Finally i found what was the problem. I solved the issue by clearing all the browser cookies. Not quite sure why this happened, but this solved it!
