Does coreos-installer support https or nfs endpoints for ignition_url and image_url during installation of RHOCP4.x?

Issue

• Does coreos-installer support https or nfs endpoints for ignition_url and image_url during installation of Red Hat OpenShift Container Platform 4.x?
• The ignition file and the image file is hosted on https endpoints. Hence, the commandline for installation is as follows.

coreos.inst=yes coreos.inst.install_dev=sda coreos.inst.image_url=https://192.168.122.180/OCP45/rhcos.raw.gz coreos.inst.ignition_url=https://192.168.122.180/OCP45/bootstrap.ign

• The installation fails with the error below.

[  127.985326] coreos-installer[821]: failed fetching image headers from https://192.168.122.180/OCP45/rhcos.raw.gz: 35

• For nfs endpoints, the command line is as follows.

coreos.inst=yes coreos.inst.install_dev=sda coreos.inst.image_url=nfs:192.168.122.180:/nfs/share/metal.raw.gz coreos.inst.ignition_url=nfs:192.168.122.180:/nfs/share/bootstrap.ign

• Whereas the error is same for NFS hosted files.
