AutoSSL results in: The domain example.tld resolved to an IP address that does not exist on this server

Symptoms

When running AutoSSL, the following is reported where example.tld is your domain name, and $IP is the IP address the domain resolves to:

CPANEL_ERROR: The domain “example.tld” resolved to an IP address “$IP” that does not exist on this server

Cause 

In order for HTTP validation to pass, the domain needs be properly configured to either resolve to the IP address that the cPanel account is configured to use on the server or to a proxy that proxies to the account IP address.

Resolution

Note: Please note, you will want to replace $example.tld with the domain that is having issues.

1. Verify nameservers match and update them if they do not.

   # whois $example.tld | grep -i "Name Server"

   # dig NS $example.tld +short

2. Confirm the DNS records return the correct IP address.

   # dig +short $example.tld 

   # dig +short www.$example.tld

3. Validate the IP exists on the server 

   # ip a | grep <IP>
