from memory and a little searching, it just means you lost the connection to the server.
more than likely something happened between you, your isp and the server location. back in the early days of jo, people with slower connections always had this issue.
i have not had that error since i went to a cable connection back around 2003ish.
irritating for sure, but the only thing that can fix it is a better isp option that offers a robust bandwidth.
