listing cluster load-balancers: %w

Error message

listing cluster load-balancers: %w

What it means

GetClusterLoadBalancers failed on the Scaleway LB API ListLBs call filtering by name 'api.<clusterName>'. Called from DeregisterInstance, so this aborts instance deregistration when the cluster's API load-balancers cannot be enumerated. The wrapped error is the SDK failure (auth, quota, connectivity).

Solutions

1. Check the wrapped SDK error for the root cause
2. Verify LB API permissions and zone configuration
3. Retry the deregistration operation
