In 8.3. Booting from an HTTP-hosted ISO image using the Redfish API

Procedure section 1.i, <hosted_iso_file>, http://webserver.example.com/rhcos-live-minimal.iso should be corrected so that it doesn't return a 404. You can do this by removing the link and only displaying the example text, or you can change the link to https://example.com/rhcos-live-minimal.iso.

Please let me know if you have questions.
