failed to list cluster servers named %q: %w

Error message

failed to list cluster servers named %q: %w

What it means

GetClusterServers failed on the Scaleway ListServers call that filters servers by cluster-name tag (and optionally instance-group tag). This propagates from findServerGroups and aborts any operation needing the cluster's machines. The wrapped error is the raw SDK failure; the request name identifies the instance group filter used.

Solutions

1. Inspect the wrapped error for auth/quota/network causes
2. Verify the cluster tag 'kops.k8s.io/cluster' format matches
3. Retry the listing operation
