WS_E_ENDPOINT_TOO_BUSY

WS_E_ENDPOINT_TOO_BUSY is a Windows Web Services API HRESULT. It means that the remote endpoint could not accept or process the request because it is overloaded or has exhausted a service-side capacity limit.

What to check for WS_E_ENDPOINT_TOO_BUSY

Check server concurrency, queues, CPU, memory, downstream dependencies and throttling policy.
Honor retry-after or service-specific backoff guidance when it is available.
Use exponential backoff with jitter and avoid synchronized retries that increase the overload.
