[ipxe-devel] Problems with pxe-virtio.rom and https

[Zombie]

Hi,

following this script 
https://gist.github.com/papamoose/e0b18d002f8686aaf767 and defining 
DOWNLOAD_PROTO_HTTPS in the general.h, I've update my proxmox 
installation's pxe-virtio.rom.

I am passing the following .ipxe file to my KVM via dhcp:

#!ipxe

set base-url http://ftp.de.debian.org/debian/dists/stretch

kernel 
${base-url}/main/installer-amd64/current/images/netboot/debian-installer/amd64/linux 
initrd=initrd.gz
initrd 
${base-url}/main/installer-amd64/current/images/netboot/debian-installer/amd64/initrd.gz
initrd https://pxeboot.myhost.net/preseed.cfg
boot


Here is my issue: iPXE keeps telling me http://ipxe.org/err/3c0920, as 
long as i don't change my initrd url to http. I've already reached out 
to the Proxmox community, whether there is anything wrong with the 
replacement of the rom. When booting the VM, HTTPS does not show up in 
the iPXE features list.

Thanks in advance,

Zombie
