Getting Started invalid username or password

I downloaded and installed 10.0.2 and followed the steps in https://www.keycloak.org/getting-started/getting-started-zip

I created a realm, user and client as instructed. However after all that the user cannot login to the test app and get invalid username or password at

http://localhost:8080/auth/realms/Camu/login-actions/authenticate?execution=45e613bf-4b0d-4e5f-abfa-178e6dd2dca6&client_id=test&tab_id=ozwyzzaqLsE

See: Getting started with Keycloak

Well Robin as I said I followed that twice and when I tried to login I got invalid user or password. I repeated with a new realm, user and client with same result. Is it because I am on a cellular network without a fixed IP address?

Try clicking on the link, and following the tutorial (which uses the containerised version of Keycloak) …

Ok well I was following the one on OpenJDK.

I will try on OpenShift
