Code:net just means that your client suddenly lost permanent connection to the server it was talking to. It can mean a problem on your end, the server's end, or anywhere on the internet in-between.

It *can* mean there's a problem with datacenters or servers, but that's usually not the case. You'd see this if, for example, your wi-fi went out.

(I'm not at all saying that's what happened. Just for example.)
