HTTP_E_STATUS_UNEXPECTED

HTTP_E_STATUS_UNEXPECTED means an HTTP client received a valid response whose status code does not fit the result set expected by the calling component. The HTTP status is evidence from the server or an intermediary; the HRESULT does not identify the root cause by itself.

What to capture

Record the numeric HTTP status, response headers, response body, request method, and final URL after redirects.
Check whether a proxy, CDN, gateway, or authentication layer generated the response instead of the origin service.
Adjust the client only after confirming which status codes are valid for the requested operation.

curl -i -v https://example.invalid/resource
