The TCP stack, NAT system, or some other software on one of the machines between the local XX.XX.XX.XX:XXXX and remote XX.XX.XX.XX:XXXXX has timed out its records about that TCP connection and closed it. Not using a connection for 30min sounds like a long timeout. Normal TCP timeouts are 5min. Each active TCP connection is using up many network resources just by staying open so letting them stay around for long periods is a bad idea.
