Hi Ron, looking at the CSV log it's reporting no reply received from your server.
Maybe something like "tcpdump -n -tttt port 123" will allow you to see the packets coming in and out so you can see if they are reaching you and if your server is replying. The checks from the server are regular so you should be able to estimate when the next one is due and/or filter for the monitoring server IP (207.171.3.17).
