     • Open a new browser tab.
     • Navigate to your domain using the HTTPS protocol (e.g., https://your-domain.com).
     • The browser should display a padlock icon, indicating a secure connection. Additionally, you can click on the padlock to view certificate details and ensure they match the details from your certificate provider.

   This should guide you through the process of updating your SSL certificate on Virtualmin using the "Update Certificate" option

   Verify the Installation:

   • Open a new browser tab and navigate to your domain using HTTPS (e.g., https://your-domain.com). You should be able to access the site without any SSL warnings, and the certificate details should reflect that it's issued by your certificate provider.
