      Description of problem:

      We created a new MC for disabling IPv6 & the pool for worker got degraded with below error
      
      Worker:   pool is degraded because nodes fail with "1 nodes are reporting degraded status on sync": "Node de1tst-mks6d-worker-gt9ml is reporting: \"machineconfig.machineconfiguration.openshift.io \\\"rendered-worker-9961311705d874cd0eb6e50025e79c15\\\" not found\""

      Version-Release number of selected component (if applicable):

      OCP v4.8

      How reproducible:

      Reproducible with adding MC for worker node on OCP v4.8 cluster on customer env

      Steps to Reproduce:

      1. Create the machieneconfig as above
      2. Then, check the operator status
      

      Actual results:

      Not able to find the newely created rendered
      
      Worker: pool is degraded because nodes fail with "1 nodes are reporting degraded status on sync": "Node de1tst-mks6d-worker-gt9ml is reporting: \"machineconfig.machineconfiguration.openshift.io \\\"rendered-worker-9961311705d874cd0eb6e50025e79c15\\\" not found\""

      Expected results:

      The MCP should progress with the new render created

      Additional info:

      They are using Cisco ACI. Initially they were facing issue with IPv6 not getting disabled by this Kbase[0]. So we suggested them doining manually using 'ipv6.method disabled' for the MC
