Configuration Manager Cannot download Microsoft 365 Apps from 2/9 release

We run in the same Error with the Update "Microsoft 365 Apps Update - Current Channel Version 2101 for x86 based Edition (Build 13628.20380)". We are on SCCM 2006 5.00.9012.1056 with all Hotfixes installed.

The following Updates where successfully downloaded:

Microsoft 365 Apps Update - Semi-Annual Enterprise Channel Version 2008 for x86 based Edition (Build 13127.21216)
Microsoft 365 Apps Update - Semi-Annual Enterprise Channel Version 2002 for x86 based Edition (Build 12527.21594)
Microsoft 365 Apps Update - Semi-Annual Enterprise Channel (Preview) Version 2008 for x86 based Edition (Build 13127.21216)

Only the Current Channel 2101 Update run into the error "Failed to download content id 16895265. Error: Invalid certificate signature"

In the PatchDownloader.log I see this errors:
