After that, regenerate a token for reactivating the VM entitlement.

 

After doing that, take the new token and use it in the CLI with below commands:

 

execute vm-license ----new token---

 

After that, select Y to reboot, and post that the License will show as working.

 

If the above steps do not work as expected, reach out to the Support team for further assistance.
