SEPM 12.1.4 - LiveUpdate not running on a schedule

I noticed over the last few days or so that our single SEPM 12.1.4 manager is not running LU on a schedule.  After a few days, clients report they are not up-to-date.  If I go to the console, and manually run LU, it all runs fine.  On the Home Page, the Latest on Manager gets in sync with Symantec.

So, can someone please let me know how to double check the correct settings and how to troubleshoot the SEPM NOT going out to Symantec to download the latest data?

Thank you!
