WS_E_ENDPOINT_DISCONNECTED
WS_E_ENDPOINT_DISCONNECTED is a Windows Web Services API HRESULT. It means that an established connection to the remote endpoint was closed or terminated before the operation completed.
Diagnostic discriminator: Determine whether the channel was established before the disconnect and record the last completed request or response boundary. A reset during an established exchange points to endpoint, proxy, load-balancer or idle-lifetime behavior rather than endpoint discovery. Before retrying, determine whether the remote side could already have committed the operation.
What to check for WS_E_ENDPOINT_DISCONNECTED
- Determine whether the disconnect occurred during connect, request upload, response download or idle reuse.
- Inspect proxy, load balancer, server and TLS logs for resets, idle timeouts or connection limits.
- Retry only if the operation is idempotent or the service provides a safe deduplication mechanism.
