ERROR_CLUSTER_INSTANCE_ID_MISMATCH

ERROR_CLUSTER_INSTANCE_ID_MISMATCH means a joining node and its sponsor node do not agree on the cluster instance identity. It commonly occurs after stale membership data, incomplete cleanup, or an incorrect rejoin path.

What to check

Verify that the node is intended to join this exact cluster and is not carrying state from another cluster.
Check the sponsor node and joining node logs together, using the same time window.
Use supported node cleanup and rejoin procedures instead of editing cluster identity data manually.
