MF_E_NET_CANNOTCONNECT
MF_E_NET_CANNOTCONNECT means the client could not establish a usable connection to the media server. It is a broad connectivity result, so capture the underlying network error rather than treating the HRESULT as the full explanation.
What to check
- Verify host resolution, route, firewall rules, proxy behavior, and destination port.
- Check that the URL protocol is enabled for the Media Foundation network source.
- Compare with a known-good endpoint using the same protocol and transport.
