Few clients are not reporting to SEPM even after upgradig to 12.1.4104.4130

Hi,

I recently have upgraded my SEPM 12.1.3 to 12.1.4 for my DB crashing issue and client reporting. But even after, I can see on 15 clients are reporting to SEPM out of 103. Can someone help me in sorting this issue out please.
