Installed 4.14.22 hostedcontrolplane in dual-stack disconnected environment. The worker nodes are failing to start installation. The agents are up but are stuck in insufficient state because they fail to download the ignition file. From agent's stateInfo:

Host cannot be installed due to following failing validation(s): This host has failed to download the ignition file from https://api.hosted-0.qe.lab.redhat.com:32236/ignition with the following error: ignition file download failed: bad status code: 511. server response: Token not found
      . Please ensure the host can reach this URL


In the ignition-server logs I see a bunch of these warnings:

    2. Install hosted cluster and register BM hosts
    3. Scale up nodepool and wait for agents to start installation
