Overview
Some people experience issues where the domain has already been pointed to the server, but the website still cannot be accessed via the domain name. What could be causing this? Let's go through the possible reasons step by step.1. DNS resolution is correct, but something else is wrong
First, verify whether the server IP address assigned to the domain is correct. Also, check if the server itself is functioning properly, as hardware or software failures on the server side are not related to the domain system itself. During resolution, ensure that the server has been properly authorized and that the necessary ports are open. For example, port 80 needs to be open for HTTP access, and if you are using SSL, port 443 must also be allowed.
2. Domain expiration
Some users overlook their domain expiration dates and forget to renew in time. Check whether your domain has expired or been deleted by the registrar. Always keep track of your domain’s expiration date and renew it before the deadline. If a domain is deleted after the grace period, it may be impossible to recover.
3. cdn binding issues
If your website uses a CDN (Content Delivery Network), you must ensure that the DNS resolution is correctly configured for the CDN service. The specific setup process depends on the CDN provider you are using. Generally, you need to bind your domain to the CDN platform first, and then configure the CDN to route traffic back to your origin server via reverse resolution.
