My phone (a Samsung Galaxy S4 Mini running Android 4.4.2) sometimes shows a message window with the text "Network interrupted; server closed". Does anybody know exactly what that means? I've tried googling it, but that doesn't get me anywhere.
The message is in English, even though I've set the phone to Dutch; other messages are in Dutch rather than English.
As far as I can see it happens when I get out of wifi range. I understand the "Network interrupted" part; seems normal if I go out of wifi range (though I'd rather expect something like "Connection lost"). What I don't understand is the "server closed" part. It seems to imply there is a server running on the phone -- does Android run some kind of server? Or is it possible that the message comes from some app that's running in the background rather than from Android itself?
