Monitor the SSL certificate status for domain names in your Alibaba Cloud CDN account. Use this page to identify certificates that are mismatched, about to expire, or already expired so you can take action before HTTPS access is disrupted.
Prerequisites
Before you begin, ensure that you have:
SSL certificates configured for your accelerated domain names. See Configure an SSL certificate for multiple domain names
View certificate status in the console
Log on to the Alibaba Cloud CDN console.
In the left-side navigation pane, choose HTTPS Center.
On the Certificate Center page, review the certificate information.
The page lists each accelerated domain name alongside its Certificate Name and Certificate Status.
Certificate status reference
| Status | Description | Action |
|---|---|---|
| Valid | The SSL certificate is valid and active. | No action required. |
| The specified domain name does not match the SSL certificate. | The domain name and the SSL certificate do not match. | Update the certificate. See Configure an SSL certificate for multiple domain names. |
| Expiring | The SSL certificate is about to expire. | Renew the certificate promptly. See Certificate renewal. |
| Expired | The SSL certificate has expired. | Renew the certificate based on your business requirements. See Configure an SSL certificate for multiple domain names. |
Query certificates using the API
To query SSL certificate status programmatically — for example, to integrate certificate monitoring into your operations workflows — call the DescribeCdnHttpsDomainList API operation.
