When you click the import button of an existing certificate, the screen goes blank. Go to: 1. System :: Certificate Management : Traffic Certificate Management : SSL Certificate List :: existing_certificate.crt :: 2. Click the 'Import' button at the bottom of the page.


You are unable to import from a certificate using the GUI.


-- Device is upgraded from 13.1.x to 14.1.x. -- Attempting to import a certificate that was created prior to the upgrade.


There are three workarounds: -- Use the GUI to download and reimport: 1. Download the cert and key. 2. Delete the cert and key from system. 3. Import it back. -- Use the GUI to rename and save: 1. Rename the cert and key, removing extensions from the file. 2. Update the config file accordingly. The Import button works successfully. -- Use tmsh to update the certs.

Fix Information

Certificates can now be imported via the GUI after upgrade.
