Chapter 1.6, " Table 1.4. Satellite Server outgoing traffic" there is a list of sites that must be reachable (console.redhat.com, cdn.redhat.com, api.access.redhat.com, cert-api.access.com).

However, while configuring satellite, after entering the manifest, it asks for "subscription.rhsm.redhat.com:443" . 

This is while installing "Red Hat Satellite (build: 6.15.5.1) Version 6.15 © 2025 Red Hat Inc."
