Is there a simple way to change the port Keycloak responds on to port 443? Is this in the admin console or maybe the standalone.xml file? I do not have any web service already using 443. Many thanks.
For anyone else trying to do this, finally figured it out. Use a port forward:
firewall-cmd --permanent --zone=public --add-forward-port=port=443:proto=tcp:toport=8443
