Re: web-management port

To add the port your use:

set system services web-management http interface ge-1/0/0.0

You will also need to confirm that the zone which this port is assigned allows the connection as well.

set security zones security-zone NameOfZone host-inbound-traffic system-services http

or

set security zones security-zone NameOfZone host-inbound-traffic system-services all
