Diagnosing `NS_E_INCOMPATIBLE_PUSH_SERVER`

0xC00D2F0C means the encoder/publisher reached an HTTP endpoint, but the response does not identify a compatible Windows Media push receiver. This is a server/protocol compatibility decision, not a failed socket write.

Evidence to collect

exact push URL, HTTP method and resolved endpoint;
request headers and the unmodified HTTP status line, response headers and small diagnostic body;
Server or protocol-identification fields and any proxy that may have generated the response;
timestamp/request ID that links the publisher trace to the receiving server log.

Focused test

Send the same push handshake to a known compatible WMS receiver and compare only the protocol response. A generic web server, reverse proxy error page or wrong publishing URL can accept TCP/HTTP while still failing this compatibility check.

Verification

Repeat the original push to the intended endpoint and require it to complete the WMS-specific handshake and create the publishing session. Do not count a successful ordinary HTTP request as proof.
