WS_E_ENDPOINT_NOT_AVAILABLE

WS_E_ENDPOINT_NOT_AVAILABLE is a Windows Web Services API HRESULT. It means that the remote endpoint is known or reachable but is not presently accepting work at that location.

Diagnostic discriminator: Compare the same endpoint during a known healthy interval or against another instance behind the same service route. A published address that resolves but temporarily refuses work indicates service readiness, maintenance or capacity state rather than a malformed URL. Honor service retry guidance and preserve the availability response before selecting failover or backoff.

What to check for WS_E_ENDPOINT_NOT_AVAILABLE

  • Check service health, maintenance status, deployment rollout and load-balancer readiness.
  • Inspect the server response or service fault for any retry guidance.
  • Apply bounded backoff and failover only when the operation and service contract support it.
