This article provides the resolution for scenarios where users receive an “Invalid License Key” error while logging in to the JSA console, even though the license is valid.
When users attempt to log in to the JSA (QRadar) web interface, the following error message is displayed:
"No license key was detected. Either the license key is invalid or has not been deployed."
This error may occur even when a valid license is already installed, and it prevents users from successfully logging in to the console.
Restart the Tomcat service on the JSA console node.
SSH to the JSA console as the root user.
Restart the Tomcat service:
systemctl restart tomcat
After the service restart, attempt to log in to the JSA console again.
Important :This issue has been permanently resolved in JSA version 7.5.0 Update Package 5 (UP5) and later releases.
Note :If the issue persists after restarting Tomcat or upgrading to a later release, please contact JUNIPER JTAC Support for further assistance.
