DNSE-230 — Sending request to server failed
Proxy tried to send a query to a selected server, but this operation failed. The reason can be either a system error (C-level message) or a network error (E-level message). Detail description of the error can be found in preceding KERN-100 or DNSE-239 message.
Proxy reaction depends on the reason. Request either will fail (C-level) or will be retried to another server (E-level).
