The only known reason for that to happen is kernel packet filtering rules
that prevent passing traffic through the stats-collector socket.  It seems
very unlikely that this "just happened" without somebody/something outside
Postgres actively breaking it.  I'd take a close look at recent system
configuration changes, particularly in the firewall area.  It wouldn't
hurt to know exactly *why* the system was rebooted, too.
