Let's Encrypt not renewing

Hi,

I am encountering problems with the renewal of my SSL certificate.
This is the error message:

SniCertificate::CertificateInvalidError: Unable to verify challenge for www.daanboertien.com: Invalid response from http://www.daanboertien.com/.well-known/acme-challenge/T1NTYSycmZIK5sV78WD_3wlCDsA-jGSTYJBsfQdVpco [2a04:1cc0:100:241::85]: "\n\n404 Not Found\n\n

Not Found

\n<p"

The Netlify-url is below:
https://reverent-brahmagupta-4a96d5.netlify.app/

I have my domainname with Strato, the DNS settings there are below:

Could you help me with this issue?
Thanks!

@DaanJTs It appears that you have your CNAME incorrectly configured.

|======================= dig CNAME(s) for =======================
| -------------------- www.daanboertien.com --------------------
daanboertien.com.
|================================================================

Instead of pointing your www subdomain at your apex domain, point it at your Netlify subdomain.

While you’re making changes, you can also update the IP address of the Netlify load balancer, which will be 75.2.60.5 going forward.

Finally, double-check that you need that AAAA record. It might be causing you issues as well.

Thank you, it took me a while to figure everything out, but it works now!!
