duckdns_not_working

/rant_start

This statement is FALSE..

I have seen that statement multiple times and never has that been the case.

DuckDNS is like a phonebook, it has one job and that is to assign a subdomain name to an IP,

If my-ha-domain.duckdns.org resolves to your IP then DuckDNS is working and you should check elsewwhere.

Verify this with nslookup on Windows or a webservice like https://network-tools.com/nslook/

nslookup:

C:\Users\user>nslookup my-ha-domain.duckdns.org
Server:  a0d7b954-pi-hole
Address:  192.168.2.200

Non-authoritative answer:
Name:    my-ha-domain.duckdns.org
Address:  127.0.0.1
