Your domain may be pointing to a server without any content on that site, or your site might be accessed through HTTPS but lacks the necessary SSL certificate. Alternatively, your domain could have an AAAA record but only work when connected via IPv4 on the hosting server. These issues can disrupt the experience of accessing the website, making it inaccessible and frustrating for users. They may not notice any errors initially but as soon as they try to access the site, they'll see a message informing them that their domain is not associated with an SSL certificate or that the site won't connect properly via IPv4.
