Question

Good morning,

I'm reviewing the logs and all works fine, we are trying to upgrade the version of SCCM to 2403, prereq are ok but at dmpdonloader.log I see the following error:

Hi,

Hope everything is going well.

1,Similar threads for your reference. The solution is to enforce TLS 1.2 for Configuration Manager.

2,We can also try to use the CMUpdateReset tool to reset an in-console update with download or replication problem. For more information, please refer to:

<SCCM Install Folder>cd.latest\SMSSETUP\TOOLS\CMUpdateReset>CMUpdateReset.exe -FDELETE -S <your SQL Server> -D CM_1 -P <package GIUD>

Hope it helps. Have a nice day!
