Help

My domain is:
lillefar.com

I ran this command:
sudo certbot --nginx

It produced this output:

Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
  Domain: www.lillefar.com
  Type:   dns
  Detail: DNS problem: NXDOMAIN looking up A for www.lillefar.com - check that a DNS record exists for this domain

  Domain: lillefar.com
  Type:   unauthorized
  Detail: Invalid response from http://lillefar.com/.well-known/acme-challenge/KTyTigfEz7n-LCf51qY5gv6tTZOAU8ubCoXKefoZNXA [2a02:4780:8:409:0:18fd:808f:7]: "<html>\r\n<head><title>404 Not Found</title></head>\r\n<body>\r\n<center><h1>404 Not Found</h1></center>\r\n<hr><center>openresty</cente"

Your DNS zone doesn't have the www subdomain specified. Only the apex domain lillefar.com has an A record.

Also, your DNS for lillefar.com has one A and one AAAA record but the servers respond differently so probably one of them is not correct. See

Let's Encrypt will prefer the IPv6 IP when present
