MF_E_NET_CLIENT_CLOSE
MF_E_NET_CLIENT_CLOSE means the control connection was closed locally by the client. It often follows cancellation, shutdown, a source stop request, or an application lifecycle race.
Diagnostic discriminator: Correlate the close timestamp with the caller’s Stop, Close, or cancellation path. A fresh session that succeeds against the same server points to local teardown ordering or a lifecycle race rather than origin availability.
What to check for MF_E_NET_CLIENT_CLOSE
- Check whether application code called stop, close, or cancellation before the network operation completed.
- Inspect concurrent state changes around media session shutdown.
- Treat this as a local lifecycle signal before looking for a server-side fault.
