failed to find server with id ("%s"): %v

Error message

failed to find server with id ("%s"): %v

What it means

While collecting a server's floating IPs, the GetInstance lookup for the instance failed. The retry-with-backoff loop returns immediately with this error, meaning the server could not be fetched by ID — typically the instance was deleted mid-operation or the API call failed.

Solutions

1. Confirm the instance still exists: openstack server show <id>
2. Retry if the failure was a transient API error
3. If the instance was deleted, abandon the floating-IP lookup
