coreos-installer fails to write ignition and images to the disk

Issue

• The RHCOS nodes being used to install a cluster in a UPI environment fail to write ignition and images to disk via the coreos-installer install command line.
• The ignition files can be manually fetched from the node and have a valid certificate as well.
• The coreos-installer install command fails while fetching images and gets redirected to builds.coreos.fedoraproject.org.
