Hint: SSL certificates are valid for one year. For user-managed SSL certificates, you are independently responsible for renewing the certificate.
This will extend an expiring SSL certificate for another year:
Log in to IONOS and select the relevant contract.
In the Domains pane, click Manage SSL Certificates.
The Domain Center opens and displays the SSL Certificates tab.
In the certificate list, click the expiration date shown in red.
To renew the certificate for the same domain, click Renew SSL Certificate.
However, if you want the certificate to be issued on a different domain, deactivate the Assign SSL certificate to the same domain option.
When you renew a GeoTrust Quick SSL Premium (SSL Starter) certificate, you can select whether you want to apply for the SSL Certificate for a domain or subdomain in the SSL Certificate section.
In the Domain area, select the desired domain and, if necessary, the desired subdomain.
Click Renew SSL Certificate.
The SSL certificate is reissued. The application should be completed within a few minutes.
Click Download Private Key to save your new private key.
You can now download the SSL certificate and install it on your server.
