I just pushed out a new dev-branch version that has the kernel update page fixed to pull the kernel list and files from github now.
@p4cm4n ipxe is loaded from the USB drive, EFI/BOOT/bootx64.efi. This file is actually the ipxe.efi kernel file taken from my FOG server in /tftproot/
@mashley If you want you could debug this a bit more, or wait until you can review the rules on the firewall.
The count on working branch and dev-branch as of today is 718 fog servers.
