Make sure you are using the CORRECT name in the dig query. You used
ddns-key.ottawatch.ca instead of ddns-update.ottawatch.ca.
Also you can delete and add in the same UPDATE operation. Remove the
first “send” in nsupdate.script.
Also ottawatch.ca has DS records but the zone is not signed. You need
to fix this as lookups are failing for anyone that is validating responses.
ottawatch.ca. 86400 IN DS 63970 8 1
FE95768ADB2B2F9E87B3C6B4210D4C21766A2EC6
ottawatch.ca. 86400 IN DS 63970 8 2
