AWS CloudFront Deployment: Fix Missing DNS Records on Nameservers

Select Language:

If you are working with a CloudFront distribution that shows as Enabled and Deployed in the AWS console or via the API, but you find that there is no DNS record for it and the domain is unreachable, you are not alone. This situation can be confusing, especially when the distribution status seems fine, but you can’t access it through your domain name.

Here’s a simple way to troubleshoot and find a solution:

First, verify that the distribution is active. Check in the AWS Management Console or use the CLI to confirm that your CloudFront distribution shows as “Enabled” and “Deployed.” Ensure that your origin, such as an S3 bucket, is correctly set up and accessible because a misconfigured origin can sometimes cause issues, although it won’t usually prevent DNS resolution.

Next, run a DNS query directly to AWS’s authoritative DNS servers to see if the DNS record exists. For example, you can run:

dig @ns-418.awsdns-52.com dnrou27ki4whi.cloudfront.net

If no records are returned, and you get an answer of “0,” it often means the DNS record hasn’t been created yet. This can happen even if the CloudFront distribution itself is active.

It’s important to know that CloudFront automatically creates the DNS records for new distributions, but sometimes this process takes longer or encounters issues. If your distribution is deployed but the DNS record isn’t available after some time, consider these steps:

– Wait a little longer, as DNS provisioning can sometimes be delayed.
– Check your distribution settings in the AWS console to ensure everything appears correct.
– Review your DNS setup, especially if you’ve set custom domain names with an alternate domain name (CNAME). Make sure to add the custom domain in the CloudFront distribution and update your DNS records accordingly.

Unfortunately, if the DNS record is missing, there isn’t a straightforward way to “force” AWS to recreate it without deleting and recreating the distribution. However, you can try the following:

– Update your distribution’s settings by adding or modifying the alternate domain names. Sometimes, this triggers the necessary DNS creation. After changing settings, deploy the distribution again.
– Wait for the DNS record to be generated automatically—typically, it should happen once the distribution is fully deployed.
– If you’ve used an alternate domain name, ensure that your DNS zone (hosted zone) has the correct CNAME pointing to your CloudFront domain.

If these steps don’t resolve the problem, and the DNS record remains missing for an extended period, it may be an AWS issue. Since you don’t have a support plan, your best bet is to check AWS forums, community support, or AWS Personal Support if available.

In summary, the most common cause for this problem is delays or issues with DNS record creation during deployment. Waiting, verifying configurations, and ensuring proper DNS records are in place usually resolve the issue. If not, reaching out through community forums or considering a support plan could be necessary steps.
