I am trying to set up my Keycloak server to show users that fail authentication a simple webpage with “Please register first”.
I have tried setting up an HTTP error page on my Apache Proxy but the response that I get from Keycloak seems to override that page.
I’ve followed the steps defined in the Keycloak documentation here Securing Applications and Services Guide for error handling, but that hasn’t worked either.
I could really use some assistance setting this up.
