No puedo configurar mi certificado SSL

Help
1

My domain is:
almasverticales.com, www.almasverticales.com

I ran this command:
sudo certbot --nginx -d almasverticales.com -d www.almasverticales.com

It produced this output:
Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:

Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet.

My web server is (include version):
Nginx 1.18.0

The operating system my web server runs on is (include version):
Ubuntu 20.04.6 LTS

My hosting provider, if applicable, is:
Hostinger (VPS)

I can login to a root shell on my machine:
Yes

I'm using a control panel to manage my site:
No

The version of my client is:
Certbot 0.40.0

You have both an IPv4 A record and an IPv6 AAAA record in your DNS

But, the IPv6 address points to a Hostinger service not your server. Hostinger creates this AAAA record automatically for new setups.

You need to update the AAAA address or remove it if you do not support IPv6.

Any client trying to use IPv6 will connect to that Hostinger service instead of your server.
Let's Encrypt favors IPv6 when an AAAA record is present.

See Hostinger article here: How to manage AAAA records | Hostinger Help Center
