Are you using docker containers? I found this problem when using keycloak docker image inside the same alfresco docker-compose file. The point is that keycloak is not started up when alfresco tries to get keycloak information. You must startup keycloak before ACS container.

Also, keep in mind that if you are using docker, you can't point to localhost to connect to keycloak, as it tries to connect to the ACS container. You should assign static ip's to the keycloak container in your docker network.

Hope it helps
