MF_E_NET_BAD_REQUEST
MF_E_NET_BAD_REQUEST means the server rejected the request as invalid. The URL, query parameters, request headers, control message, or requested publishing point may be malformed.
Diagnostic discriminator: Use the same endpoint and network path with a known-good request. If the control succeeds, preserve the rejected request exactly as sent and the server parsing or validation result; changing codecs or playback timing will not repair a malformed request.
What to check for MF_E_NET_BAD_REQUEST
- Compare the request URL and headers with a known-good player request.
- Check URL encoding, path mapping, and any proxy rewrite rules.
- Review server logs for the specific parsing or validation failure.
