      Description of problem:

      While testing on https://github.com/openshift/machine-config-operator/pull/4800#issuecomment-2628801965, we found the worker can't fetch Ignition successfully so it couldn't be started well.
      
      The worker machine console serial log shows:
      
      �[K[�[0m�[0;31m*     �[0m] A start job is running for Ignition (fetch) (50min 30s / no limit)
