I have setup Jupyterhub in my AWS server, I am able to access server and visit login page. But after adding allowed users and admin\_user to config file when i try to login it says Incorrect Username or password.

Is there any solution to fix this?

Note: Server is setup without Docker / kubernetes.

Did you restart the service after config is updated?
