The usual cause of lost connections is a stateful firewall (or NAT, etc)
between the client and server. If a connection stays idle for too long,
the firewall may consider that connection dead and reject subsequent
traffic on it. The driver doesn't discover this until the next time the
connection is used.

If that's not it, at a minimum we'd need to see a stack trace of the
error you get to diagnose this any further.
