failed to find server groups: %w

Error message

failed to find server groups: %w

What it means

Returned by GetCloudGroups when the helper findServerGroups fails to list Scaleway servers tagged for the cluster (its own ListServers call errored). This wraps the underlying SDK error, so the real cause (bad credentials, API outage, invalid zone) is in the chained error text.

Solutions

1. Inspect the wrapped error to identify the SDK failure (auth, quota, connectivity)
2. Verify SCW credentials, zone, and project ID are configured
3. Retry: transient Scaleway API failures are common
