You can refresh the certificate of a device to authenticate VPN and SSL. When you add a device manually, you need to synchronize the certificate, which can be done on more than one device at a time.
To refresh the device certificate:
The Refresh Device Certificates page appears.
You can also right-click the selected device and select Refresh Certificate.
The Job Details page appears and provides the status of the certificate synchronization.
The list of available certificates on the device appears.
Refreshing the device certificate process is complete.
