Incoming connection from 10.0.0.221, fd 53.
Incoming connection from 10.0.0.221, fd 53.
[WS 10.0.0.221/53] Connected
[WebSocket fd:53] read-error (128: Socket is not connected), disconnecting (recv)
[WS 10.0.0.221/53] Disconnected

It is not clear why the socket ends up in this state even though the browser indicates that it is still connected and reconnects a second time and remains connected.
