The system displays a security alert with the following text: The security certificate has expired or is not yet valid.
This is a browser-based popup that informs the user that the certificate used by the server is not valid. The problem is a configuration error on the server and can not be influenced by NWBC. We highly recommend that you read 7.7 Certificate Error Popups in the Browser. The only possible solution for this problem is to ask the system administrator to configure the digital certificates used in the server to be valid.
