I am trying to update the Splunk Add-on for Nessus from version 3.0.2 to 5.1.1, but got error message "An error occurred while installing the app: 400" Any ideas or suggestions? Thank you!
3.0.2 is truly an old version. Is it possible for you to reinstall the latest version and migrate the configuration manually?
That's good point. Thank you for the suggestion!
