comment Protected Client Server communication advice
If the TCP three-way handshake was done, then the server actually expects incoming connection. If a client connects, and then the client drops the connection instead of sending the ClientHello, it is understandable that the server logs something which should be "the client closed the connection before sending his ClientHello" but for many implementations, the log entry will probably be more cryptic and say something like, indeed, "unspecified error". This does not tell you more than you already knew.
