PVE Installer PXE boot did not work with FTP Server

[fireon]

Hello all,

we have two ways here for us PXE Grubconfig to install Proxmox Server (EFI). The old way:

menuentry 'Proxmox 6.2' --id proxmox62 {
  linuxefi /proxmox62/linux26 vga=791 video=vesafb:ywrap,mtrr ramdisk_size=2000000 linux ext4 maxroot=60 swapsize=16 splash=verbose
  initrdefi /proxmox62/initrd.iso.img
}

this is working, but need about 3-5 minutes to boot.
The new way. Did not work, but should be a lot of faster. Other machines like Ubuntu do this that way.

menuentry 'Proxmox 6.2 Faster' --id proxmox62-ftp {
  linuxefi /proxmox62/linux26 vga=791 video=vesafb:ywrap,mtrr ramdisk_size=2000000 linux ext4 maxroot=60 swapsize=16 splash=verbose
  initrdefi url=ftp://data.tux.lan/pxe-iso/proxmox/initrd.iso.img
}

Here we get the error Message:

Error File not found.

.... Press any key to continue

After that is kernel panic. So what i'am doing wrong?

Very Thanks.

Ok, changed.

menuentry 'Proxmox 6.2 Faster' --id proxmox62-ftp {
  linuxefi /proxmox62/linux26 vga=791 url=ftp://data.tux.lan/pxe-iso/proxmox/proxmox-ve_6.2-1.iso video=vesafb:ywrap,mtrr ramdisk_size=2000000 linux ext4 maxroot=60 swapsize=16 splash=verbose
  initrdefi /proxmox62/initrd.img
}

initrd.img is loading right, but no iso. Error Message is attached.
