  If you click on the Advanced button, and then click on the link to proceed to the web page, you can successfully log into the NES Administrator Console.

Cause

This behaviour occurs when the network terminal that you used to connect to the NES Administrator Console does not have the root certificate for the trusted root Certificate Authority installed as a trusted root.

Resolution

Import the root certificate into the Trusted Root Certificate Authority store. See Importing root certificates for more information.
