Hello!
I have, what is probably a very simple question- I am trying to configure dynamic DNS, with DuckDNS. However, I have an issue where the cached IP is always 0.0.0.0.
Even after I manually hit "Save and Force Update" in the DDNS settings, it remains as 0.0.0.0. I am using a VPN (connected to Mulllvad, via WireGuard with a static IP), could that be the reason why it is not working?

I am very new to this, and I think that I've likely just missed out a step, but was unable to find a guide or any examples online. Sorry if this is quite a basic question, but I would be super grateful, if anyone could point me in the right direction- thank you very much in advance ;D
This is what I have done so far:
Under Services --> Dynamic DNS, I added a new client.
I set the Service type to DuckDNS and interface to monitor to LAN, added in the hostname I registered through DuckDNS, and double-checked, and inserted my DuckDNS credentials.

Next, under System --> Settings --> General --> Networking, I enabled "Allow DNS server list to be overridden by DHCP/PPP on WAN"

---
I then went to System --> Settings --> Cron, and added a new job to update the IP for DuckDNS every morning, using the standard "Dynamic DNS Update" command

Under Services --> DHCPv4 --> [LAN] --> Dynamic DNS, I left it as is, and did not Enable registration of DHCP client names in DNS

My DuckDNS account currently shows the correct IP, and seems to all be in order

Annoyingly, a while ago I did find a good tutorial (https://bachelor-tech.com/home-server-router-all-in-one/opnsense-dynamic-dns-set-up-with-duckdns/), but the website is now down, and I can't fully remember all the content, and doesn't seem to be archived anywhere- I'm slapping myself for not downloading it!
Any suggestions, would be really appreciated- thank you very much in advance!
Any ideas would really help :-*
Interface to Monitor should be WAN not LAN.

Thank you @AhnHEL - I feel dumb for not spotting that! Thank you very much for your help 🙌
Glad you got it sorted. ;)
