ERROR_CLUSTER_INVALID_NETWORK_PROVIDER

The Cluster service rejected the network provider configuration used for the request. This is different from a simple unreachable node: the provider or protocol binding itself is not acceptable to the cluster.

What to check

Use cluster validation to identify unsupported or inconsistent network configuration across nodes.
Check that all nodes expose the intended physical and virtual adapters consistently and that cluster traffic is not bound to an inappropriate management-only interface.
If a third-party network component is involved, correlate its installation or update with the first cluster error in the log.
