The subdomains adguard.DOMAIN, wg.DOMAIN and auth.DOMAIN should also point to the VPS. Is that the case for you?

I have this problem, can you help me? I created a service in AWS and released ports 80,443,53,51820,22. my free domain is from duckdns, I already indicated my IP but even so, during installation, the following error message appears: DNS problem: SERVFAIL looking for CAA for deviceconnectionvpn.duckdns.org - the domain nameservers may be faulty

Can this be done using Duck DNS? I mean can I create or edit sub-domains and point them to the same IP address using Duck DNS?

@sekhar989 DuckDNS automatically creates a wildcard CNAME record for the subdomains.
So when you create an example.duckdns.org domain, *.example.duckdns.org will automatically resolve to the same IP address

Ok ok! However, I'm still facing the issue. Please take a look at the screenshots for details.

Firstly, I appreciate the hard work and sharing it with us. Thank You so much for this.
I'm a noob at this, so please don't mind if I am asking stupid stuff.
I would greatly appreciate any help.

make sure anything else is not currently using port 80 otherwise it will fail
run the command below to see if its currently busy
sudo ss -tlnp | grep 80

Yep, I did check that. There was nothing else running on port 80. I just had to wait for some time.
It's all configured now.
However, I see that iPlayer detects my location. I checked for DNS leaks, there was nothing.
Any ideas would be appreciated.
