By default the HANA Cockpit 2.0 uses XSA port based routing, so each application is accessible via a different port but all on the same host.
In hostname based routing, the differentiation for requests to different apps is done via different hostnames (see note 2245631).
The hostname based routing can be activated for HANA Cockpit 2.0 by calling the installer with the parameter --xs_routing_mode:
The cockpit app is then accessible via the hostname hanacockpit-sap-cockpit-web-app.<domain>
The cockpit admin app is accessible via the hostname hanacockpit-sap-cockpit-admin-web-app.<domain>
