PENDING All SCCM Clients Inactive in Console

[MagnumVP]

When I view MECM I can see all clients but they all show Inactive. Most of the Software Scan and Hardware Scan shows 2/24/2022 as the last communication date.
Where can I begin to look as to why? All the current logs don't go back that far.

Is there a way I can flush all logs, reboot the server and look through the logs to see where the issue may be. Can't restore, so I need to resolve this issue in it's current state.

Do you see this error after re-install ccmsetup? or re-built a new server without decommissioning the existing settings?

Could be one firewall port blocked, review the communications between SCCM and client isn't is blocked.
