NEW A few Servers are not patching from SCCM.

[heeramoni]

Hi Guys,
Wonder if you can advice me please.
Server patching is working perfectly for most of the servers but not for 2-3 servers. PKI and Client Activity is "Active" for those client server. May I get advice what log file I should check in the client side? What else I should do to fix the issue?

I have tried few times install/reinstall the client from SCCM
Installed/requested for the SCCM client certificate and installed the certificate successfully .

Regards,
