Clients cannot be pointed to the new SEPM Server

Hello all , I deployed a communication update package from a New SEPM server to point clients connected to existing old SEPM to this new SEPM server. The communication is being deployed sucuesfully to the clients but for some reaons they are not appearing in the new SEPM console . It is not giving any error when the communication update package is being deployed.  Please find the attached screenshot.

Thanks
