Blason has not shown his full config, but it must be listening on port 15455 to be receiving the NOTIFY message, as shown by the log entry. The master has: notify explicit; also-notify { 2.2.2.2 port 15455; }; This tells the master to notify 2.2.2.2 on port 15455. There is no notify on port 53. What made you think that port 53 is being used?
