My guess is that the server received a TCP RST, indicating that the client's
socket has gone away, and the the error message is the same for a RST received
during connection setup and a RST received later on.

During connection setup, it absolutely makes sense to say that the "client has
actively refused the connection" if it responds to a SYN packet with RST...
