When we enable techpreview and we try to scale up a new node using a 4.5 base image, the node cannot join the cluster

$ oc get clusterversion

Always
    

    1. Create a new machineset using a 4.5 base image and a 2.2.0 ignition version
    
    Detailed commands to create this machineset can be found here: [OCP-52822-Create new config resources with 2.2.0 ignition boot image nodes|https://polarion.engineering.redhat.com/polarion/#/project/OSE/workitem?id=OCP-52822]
    
    
    2. Scale up this machineset to create a new worker node
    
    

    The node cannot join the cluster. We can find this message in the machine-config-daemon-pull.service in the failed node

    Nodes should join the cluster
    

    If techpreview is not enabled, the node can join the cluster without problems
    
    The podman version in a 4.5 base image is:
