It is caused by firewalls, routers, network port translators and network
address translators (or any other similar device) that imposes a fixed
timeout on the length of time that inbound udp packets can be received
in response to outbound packets.

If the timeout period is less than the cache manager probe period, it is
likely that this error will be seen.

I would check the firewall rules on the local machine.

Same here.  Check the firewall rules on that machine.
