The "xx days" are decreasing every day how to fix this issue?
This is MC 3.1.x base OS bug. This bug is fix in MC 126.96.36.199
Running "licensing load" or "show licenses" would trigger this bug
Management Center Virtual-Appliance running 3.1.x
Recently upgrade MC-VA to 3.1.x
Upgrade MC to version 188.8.131.52
Restart Management Center.
You can restart by running "restart" in MC's CLI, privilege mode
Once rebooted, it may take up to 24 hours for the message to disappear.
Note: Running "licensing load" or "show licenses" command on MC 3.1.x CLI would trigger the issue again on which another restart is needed
