To connect via http you need have CloverETL Server installed and running. The installation of CloverETL Server is described in CloverETL Server Documentation.

With the HTTP connection, you do not need configure CloverETL Designer. Simply start your CloverETL Designer. With this Designer, you can create your CloverETL Server projects using the following default connection to Server: http://localhost:8080/clover where both login name and password are clover.
