MF_E_NET_BAD_CONTROL_DATA
MF_E_NET_BAD_CONTROL_DATA indicates invalid control-plane data was sent during the streaming session. The cause can be malformed framing, a client/server version mismatch, or a proxy that modifies the control channel.
What to check
- Capture the control-plane exchange only in a safe test environment and compare it with the expected protocol.
- Confirm that the client and server are using a mutually supported media protocol.
- Check proxies and protocol-aware gateways that may rewrite or truncate control messages.
