WININET_E_CHG_POST_IS_NON_SECURE
WININET_E_CHG_POST_IS_NON_SECURE is a WinINet HRESULT. It means that a redirect or navigation would move a POST submission from HTTPS to HTTP. Continuing could expose the request body or credentials to an insecure transport.
What to check
- Reject or explicitly review the downgrade rather than automatically forwarding the POST body to HTTP.
- Correct the server redirect and configured endpoint so that form and API submissions remain on HTTPS.
- Check load balancer, reverse-proxy and application redirect rules for an incorrect external scheme.
