Description

This article describes a behavior where a certificate error is generated when exporting data from the FortiNAC Admin UI.
Scope FortiNAC-F v7.6.
Solution

Example:

  1. In the FortiNAC GUI, navigate to Users & Hosts -> Adapters.
  2. Select Export. 

 

The error 'Cannot create export files without a valid certificate' is displayed.

 

export errorexport error

 

This behavior can occur when using an insecure HTTPS connection, as indicated in the browser address bar, for example:

 

page marked as not securepage marked as not secure

 

This error message appears per design.

 

Other exportable data affected by this include:

  • Hosts.
  • User accounts.
  • Endpoint compliance.
  • Audit Logs.
  • Event Logs.

 

To export data, the browser must be connecting to the FortiNAC Admin UI using a secure URL (e.g., https://<hostname>:8443/).  

 

How to upload certificates is explained in the Admin UI Certificate Target description under Server Certificates in the Administration Guide.
