PENDING SCCM 1809 to 1902 after upgrade issues

[sureshdgm]

Hello Prajwal ,
I've upgraded sccm 1809 to 1902 last Saturday, after that i got many errors in server "LocationServices" The log says "Failed to send management point list Location Request Message to "my sccm server name"

"MP_Status" The log says "Mp Status: processing event: SMS_RemoteClient_ManagementPointCertificate_CrossVerificationFailure, for machine: "client machines"

when i cross-checked all of the client machines "LocationServices" says "Failed to validate the certificate '' from management point " my sccm server name.

"CertificateMaintenance" the log says "Failed to verify signature of message received from MP using name 'my sccm server name'

PXE boot not working and client not received patches.

Please find the attached all logs and help me ASAP.

Did you try uninstalling MP role and install it back ?.

For ADK.jpg - Have you tried booting the system into Safe Mode to see if it makes a difference? This should help rule out third-party programs and shell extensions that could could be interfering.
