waiting for load balancer deletion completion: %w

Error message

waiting for load balancer deletion completion: %w

What it means

PollUntilDone failed while waiting for the load balancer deletion LRO; the delete was accepted but the operation failed (often because dependent resources such as public IPs or NICs still reference the LB).

Solutions

1. Remove dependent resources (public IPs, NICs, backend pools) referencing the load balancer and retry
2. Inspect the wrapped error for the specific provisioning failure
