Assign a new key pair for any of the active HTTPS listeners. For details about the available listeners, see HTTPS listeners. Click Security and then go to Key Pairs. Click the Pencil icon, and then click Assign HTTPS Listener for the key pair. Use the Listeners list to select the HTTPS listeners for which the key pair should be used. Note: Changes to an HTTPS listener's active key pair are used for all new connections, but existing connections continue to use the old configuration. Click Save.
