SCCM version 2002 all clients showing inactive

[amakusa007]

I am in need of help here. We have recently discovered that all of our client are showing as inactive since 7/10/2020. The only thing we had back then was the certificate authority renewal of certificates for all computers. we have renew all certificates on all the computers and servers but no luck on sccm. I have updated the certificate inside the distribution point with the new certificate and still showing inactive on all clients/servers. I have tried switching between HTTP and HTTPS as well in the distribution point under administration > server and site roles and nothing. Rebooted the server also and no changes. all certificates as well on the mmc certificate console panel are updated as well.
