ERROR_CLUSTER_SYSTEM_CONFIG_CHANGED

The Cluster service deliberately aborted the operation because its assumptions changed mid-flight. Common examples include network changes, service updates, configuration automation, or concurrent cluster management.

What to check

Stabilize the node configuration, network adapters, and deployment state before retrying.
Avoid applying updates, renaming adapters, changing IP configuration, or running multiple cluster jobs during a join.
Use the cluster log to identify the specific change that caused the operation to abort.
