Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is:
www.gianlustuff.net
The zone is hosted on R53 (AWS) and the IP is updated with a dynamic dns client and linked with a CNAME.. It always worked this ways until the latest cert update, and I'm not finding the culprit of the issue.
I ran this command:
Embedded into HestiaCP (nginx)
It produced this output:
Error: Let's Encrypt validation status 400 (gianlustuff.net). Details: 400:"DNS problem: SERVFAIL looking up A for www.gianlustuff.net - the domain's nameservers may be malfunctioning; DNS problem: SERVFAIL looking up AAAA for www.gianlustuff.net - the domain's nameservers may be malfunctioning"
My web server is (include version):
Nginx/Apache
The operating system my web server runs on is (include version):

I can login to a root shell on my machine (yes or no, or I don't know):
Yes
I'm using a control panel to manage my site (no, or provide the name and version of the control panel):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):
