"Failed to Validate Your Plugin License" or "Your Add-on License Is Invalid" Error When Registering Balsamiq for Confluence Server or Jira Server

You get these errors if you enter a license you purchased from Balsamiq in the plugin’s licensing box provided by Atlassian’s Universal Plugin Manager.

That text area only accepts Atlassian Marketplace-generated licenses. To enter your Balsamiq-generated license information, click on Configure, and you’ll see this screen:

Click on “Balsamiq”, and you’ll see this screen:

Enter your license name and key there, and it will work.

Once you have successfully registered your Balsamiq-generated license, the Atlassian registration screen will still show your plugin as “Unlicensed.”

Heads up: If you have a Marketplace trial license installed, you might not see a Configure button at all. Delete your Marketplace license key and hit update to make the Configure button re-appear. This will allow you to enter a Balsamiq-issued license instead.
