Hey, sorry for the late reply. You should use --http-port instead of http.port, then it’ll work CLI is all dash-case. The new Version of Keycloak.X, which will be shipped together with KC16, will bring many enhancements, e.g. command completion for bash/zsh, so feel free to try it out by getting latest main from github and building via mvn clean install -DskipTests -Pdistribution
