In my experence there isn't really a case where the client gets
disconnected (like a crash) and then needs to reconnect.
For me the client always stays enabled, but if there is a problem at
the remote end then packets don't go anywhere.

In other words the traffic might get dropped by the remote (feels like
no traffic *at all*), but I've never seen a situation where I was
accedentially sending unencrypted traffic.
