@Hanz inits do not rely on the fog client (hostname changer, printer manager, etc…) for booting the host. While it is possible to load ipxe https it is not enforced nor would I recommend it either.
I don’t know what issues you were having or why but if you rebooted the host after re running the installer the only guess I would have is the inits were not finished downloading when the host was trying to use the files.
For now I’m going to solve this thread as I’m fairly sure it is fixed after running the installer.
