You might want to check whether, for example, a long-lived SSH session between client and server, without TCP or SSH keep-alives, is able to survive the night without activity, and not be reset as soon as you try to use it in the morning. Failing that, the last few packets of output of a tcpdump of the connection on the client side, with timestamps, might be useful in diagnosing the problem.
