Caused by: end of file before message length reached

Reproduction Steps

PXE boot. Here is my iPXE config (it is provided by Matchbox to match a configuration with a machine):

	"boot": {
		"kernel": "http://10.20.30.100:8000/image/fedora-coreos-31.20200210.3.0-live-kernel-x86_64",
		"initrd": [
			"http://10.20.30.100:8000/image/fedora-coreos-31.20200210.3.0-live-initramfs.x86_64.img"
		],
		"args": [
			"ip=dhcp",
			"rd.neednet=1",
			"initrd=fedora-coreos-31.20200210.3.0-live-initramfs.x86_64.img",
			"coreos.inst.image_url=http://10.20.30.100:8000/image/fedora-coreos-31.20200210.3.0-metal.x86_64.raw.xz",
			"coreos.inst.ignition_url=http://matchbox.yuzu.local:8080/ignition?uuid=${uuid}\u0026mac=${mac:hexhyp}",
			"coreos.inst.install_dev=sda",
                        "coreos.inst.insecure=yes",
                        "random.trust_cpu=on",
			"console=tty0",
                        "systemd.journald.max_level_console=debug"
		]
	}

Other Information

After it fails I can access the emergency mode for maintenance.
From there I could confirm that the guest gets its IP config with DHCP and that it has access to the internet.
I didn't find anything obvious about the failure. I am not sure where to look at, based on this "end of file before message length reached" error message.

The image I use is fedora-coreos-31.20200210.3.0-metal.x86_64.raw.xz.
I use a copy of the image in a local web repo and I can confirm its signature and integrity :

# gpg --verify fedora-coreos-31.20200210.3.0-metal.x86_64.raw.xz.sig  fedora-coreos-31.20200210.3.0-metal.x86_64.raw.xz
