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. [crt.sh | example.com](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: [viptoolhub.com](http://viptoolhub.com)

I ran this command: sudo certbot --nginx -d **[example.com](http://example.com)** -d **[viptoolhub.com](http://viptoolhub.com)**

It produced this output: Saving debug log to /var/log/letsencrypt/letsencrypt.log  
Requesting a certificate for [viptoolhub.com](http://viptoolhub.com) and [www.viptoolhub.com](http://www.viptoolhub.com)

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

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.

Some challenges have failed.  
Ask for help or search for solutions at [https://community.letsencrypt.org](https://community.letsencrypt.org). See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.

My web server is (i don't know):

The operating system my web server runs on is (ubantu):

My hosting provider, if applicable, is: digitalocean

I can login to a root shell on my machine (using new username):

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):

First and foremost, before trying to issue TLS certificates you should get you website in working order.

Your apex domain currently has 4 A and 3 AAAA records:

```nohighlight
$ dig +short viptoolhub.com
172.64.52.210
172.64.53.21
172.64.49.209
128.199.9.216

$ dig +short aaaa viptoolhub.com
2606:4700:52::ac40:31d1
2606:4700:52::ac40:34d2
2606:4700:5a::ac40:3515

```

The IP starting with 128 is owned by digitalocean. All of the others are owned by cloudflare. Since your domain isn't managed by cf: you and your visitors will experience issues, I'd advise getting rid of cloudflare IPs.

As for the particular error you're experiencing: there are no A or AAAA records for your `www` subdomain. Either add them, or don't attempt getting a certificate for this subdomain.
