SOLVED SCCM 2409 - Unsupported site server operating system meets...

[bcmurari]

Good afternoon!
I am running the prerequisites check to update SCCM to version 2409, but I get this error:
[Failed]: Verifies that the site server operating system meets the minimum requirement for site server installation. https://go.microsoft.com/fwlink/?linkid=841654

The database server is running Windows 2019 Standard 1809. I have verified that the operating system version is correct. Is there another possibility to fix this or can I just update to 2022?

What appears in the log is practically the same error:
Unsupported site server operating system version for Setup; Error; Configuration Manager site systems can only be installed on computers running supported operating systems. https://go.microsoft.com/fwlink/?linkid=841654

Thank you in advance for your help.

Are there any other site systems that are running unsupported version of Windows server?

Hello Prajwal
Greetings!
Are you questioning all servers including DPs or just Primary, DB and MPs? If it is just the Primary, DB and MP's are all in the same 2019 1809 version.
Thanks

That should be ok. Can you run the prerequisite check again?

We discovered the problem, the Remote Registry service was stopped. We activated it and ran prereq and it worked

Thank you very much for your help.
