error fetching KopsControlPlane %v: %w

Error message

error fetching KopsControlPlane %v: %w

What it means

Fetching the KopsControlPlane resource named by the CAPI cluster's controlPlaneRef from the API server failed; a Kubernetes API error (not-found, RBAC, connectivity) rather than a malformed reference — the reference was already validated.

Solutions

1. Check the wrapped error: NotFound means the KopsControlPlane does not exist yet or the name is wrong
