If only https is enabled the admin console shows no server url at Runtime -> Hosts -> <Host name> -> <Server name>.

There is a filter for socket bindings with a name started with http in org.jboss.hal.core.runtime.server.ServerUrlTasks which takes the first such binding regardless it is bound (enabled) or not, see [1]. This then leads to n/a at line 128, see [2].
