This error indicates that the HOSTID linked to your up.time license key does not match the HOSTID of your current monitoring station.
There are a few reasons why this error may occur:
- You have installed the Monitoring Station on a new system and are still using the same license key.
- You made changes to your system hardware.
- You have re-installed your Operating System.
- If your system is a VMware instance, the UUID or MAC address for the instance may have changed.
Regardless of the root cause, you will need to generate a new license key that matches the new HOSTID (Finding Your HOSTID). You can do this by logging into the uptime licensing portal, expand the Deployment Name and click on Re-host License Key.
