This article explains how SSL certificates secure the connection between your visitors’ browsers and your website, and why domain configuration issues may prevent a certificate from renewing automatically.
You will learn how to identify the most common causes, update your CNAME record, and check that your website is accessible securely again.
1. Understanding the most common issues
You are receiving SSL revalidation emails from Cloudflare
Learnybox previously used Cloudflare to generate and manage SSL certificates.
At that time, domains configured for Learnybox generally used a CNAME record pointing to a target ending in:
cdn.cloudflare.net
When you continue to receive SSL revalidation emails from Cloudflare, it often means that an account or certificate is still active with that provider.
This does not necessarily mean there is a problem with your website.
Your website displays an SSL error or is no longer accessible
In some cases, the subdomain configured in your DNS settings may still point to an old Cloudflare target ending in:
cdn.cloudflare.net
Learnybox has not used Cloudflare to manage SSL certificates for several years.
Your CNAME record should now point to:
ssl.learnybox.com
When your domain continues to point to an old Cloudflare target, the SSL certificate may no longer renew automatically. This can cause security errors or prevent visitors from accessing your website.
2. Correct your domain configuration
Update the CNAME record
Open the DNS management interface provided by your domain registrar or DNS host.
Locate the subdomain concerned.
The subdomain is not necessarily www.
Check the target currently configured for its CNAME record.
When it points to an address ending in cdn.cloudflare.net, or to any other incorrect target, replace it with:
ssl.learnybox.com
Save your changes.
Allow time for the DNS update to propagate. Depending on your DNS provider, this may take up to 48 hours.
Once propagation is complete, the SSL certificate can be generated or renewed automatically.
Best practices
Once the CNAME record correctly points to ssl.learnybox.com, do not modify it again.
The SSL certificate will continue to be generated and renewed automatically as long as this configuration remains in place.
3. How to check that the issue has been resolved
After DNS propagation:
open your website using HTTPS
check that your browser indicates that the connection is secure
confirm that your website pages load without an SSL error
When the issue persists after updating the CNAME record and allowing time for DNS propagation, contact Learnybox Support and provide the domain concerned.
At this stage, your domain points to the configuration expected by Learnybox, and your SSL certificate can renew automatically.
