HTTP_E_STATUS_UNEXPECTED_REDIRECTION

HTTP_E_STATUS_UNEXPECTED_REDIRECTION means the requested operation received a 3xx response when the caller expected a final response. A redirect can originate at the application, a reverse proxy, an authentication gateway, a CDN, or an HTTP-to-HTTPS migration rule.

What to verify

Inspect the Location header and the complete redirect chain.
Check for redirect loops, host-name changes, lost query parameters, and changes between HTTP and HTTPS.
For non-idempotent requests, make sure the client redirect policy does not replay a request body or credentials in an unsafe way.
