Client not upgrade through Webserver

Hi all, 

I am facing a new deployment message/status while upgrading the Client from version 12.1.4013 to 12.1.6867 through Webserver:

"The Client Decided to reject the upgrade package ,Client has ignored upgrade package ,version 12.1.6867.6867"

But when I upgrading the Client throught SEPM, it that install successful.

Can any one help me if they had the same issue and got a resolution ?
