Configuring CNAME and _acme-challenge DNS records for custom domain SSL in Adobe Experience Manager Dynamic Media
This article explains how to configure the required CNAME records, including the _acme-challenge record, to enable SSL for a custom domain in Adobe Experience Manager Dynamic Media.
Description description
When setting up a custom domain for use with Adobe Experience Manager Dynamic Media, you must configure specific DNS CNAME records. These records are necessary for both domain forwarding and SSL certificate validation.
The main CNAME record points your custom domain to the Dynamic Media delivery endpoint, while the _acme-challenge CNAME record is required to validate domain ownership during SSL certificate provisioning.
If the _acme-challenge record is missing or incorrect, SSL setup will fail, and your custom domain will not be secured.
Resolution resolution
Follow the steps below to resolve the issue.
-
Log in to your DNS provider’s management console for your custom domain.
-
Add or verify the following CNAME records:
-
For domain forwarding:
- Name:
<your-custom-domain> - Target:
wildcard.scene7.com.edgesuite.net(or the value provided by Adobe)
- Name:
-
For SSL certificate validation:
- Name:
_acme-challenge.<your-custom-domain> - Target:
<challenge-value>(this value is provided by Adobe during the SSL provisioning process)
- Name:
-
-
If you have not received the
_acme-challengevalue, contact Adobe Support to obtain the correct value for your domain. -
After updating your DNS records, use a DNS propagation checker (such as dnschecker.org) to confirm that both CNAME records are publicly visible and correctly set.
-
Once DNS propagation is complete and both records are visible, notify Adobe Support so SSL provisioning can proceed.
-
Verify that your custom domain is accessible via HTTPS once SSL provisioning is complete.
