Why Your Certificate Shows Expired Even After Renewal

It can be frustrating to renew your SSL certificate only for Domainyze (or other tools) to still report it as expired. This usually doesn't mean Domainyze is wrong, but rather that there's a step missed or a delay in the update process.

Here are the most common reasons:

1. New Certificate Not Installed on Server

• Renewal ≠ Installation: Renewing your certificate with your provider generates a new certificate. This new certificate must then be installed on your web server (or CDN, load balancer, etc.). Many users renew but forget the installation step.
• Old Certificate Still Active: If the new certificate isn't installed, your server will continue to present the old, expired certificate to visitors and to Domainyze's checks.

2. DNS Caching or CDN Propagation

• If you use a Content Delivery Network (CDN) or a proxy service (like Cloudflare), it might be caching the old certificate. You may need to purge the cache in your CDN settings for the new certificate to propagate.
• Local DNS caching can also sometimes cause delays, but this is less common for SSL issues specifically.

3. Incorrect Installation

• Even if you've installed it, the new certificate might be incorrectly configured (e.g., wrong certificate chain, missing intermediate certificates). This can lead to invalid certificate errors, which Domainyze might interpret as an issue.

4. Domainyze Cache

• While Domainyze performs regular checks, there might be a short delay (a few hours depending on your plan) before our system picks up the absolute latest changes. You can always trigger a manual check for an immediate refresh.

What to Check

1. Verify Installation: Use an independent online SSL checker tool (e.g., SSL Labs, SSL Shopper) to verify that your website is presenting the correct and current SSL certificate.
2. Clear Caches: If using a CDN or proxy, clear its cache.
3. Restart Web Server: Sometimes, a web server (Apache, Nginx, IIS) needs to be restarted after installing a new certificate for changes to take effect.
4. Contact Support: If all else fails, contact your web host or SSL certificate provider's support for assistance with installation.

Once the new certificate is correctly installed and accessible to the public internet, Domainyze will update its status during the next check.
