Install or Update a TLS/SSL certificate
Follow the instructions of your certificate provider
Updating or installing a TLS certificate, or its older predecessor SSL, often depends on the format of the certificate and the certificate provider. For more exact instructions reach out to your certificate provider for details. For example, GoDaddy has specific instructions for installing their certificates on IIS.
