When you have a HCP running and it's creating the HostedCluster pods it renders this IgnitionProxy config:

defaults
  mode http
  timeout connect 5s
  timeout client 30s
  timeout server 30s

frontend ignition-server
  bind *:8443 ssl crt /tmp/tls.pem
  default_backend ignition_servers

backend ignition_servers
  server ignition-server ignition-server:443 check ssl ca-file /etc/ssl/root-ca/ca.crt

This Configuration is not supported on Ipv6 causing the worker nodes to fail downloading the Ignition Payload

MCE 2.4
OCP 4.14

Always

1. Create a HostedCluster with the networking parameters set to IPv6 networks.
2. Check the IgnitionProxy config using: 

oc rsh <pod>
cat /tmp/haproxy.conf

Agent pod in the destination workers fails with:

Jul 26 10:23:44 localhost.localdomain next_step_runne[4242]: time="26-07-2023 10:23:44" level=error msg="ignition file download failed: request failed: Get \"https://ignition-server-clusters-hosted.apps.ocp-edge-cluster-0.qe.lab.redhat.com/ignition\": EOF" file="apivip_check.go:160"

The worker should download the ignition payload properly
