Windows Server 2012 is the server version of Windows based on Windows 8 and succeeds Windows Server 2008 R2, which is derived from the Windows 7 codebase, released nearly three years earlier. Two pre-release versions, a developer preview and a beta version, were released during development. The software was generally available to customers starting on 09-04-2012, by Microsoft. A successor was released on 10-18-2013, entitled Windows Server 2012 R2. Microsoft ended mainstream support for Windows Server 2012 on 10-09-2018, and extended support will end on 10-10-2023.
Since you're using volume license product keys you should have also used volume center download so the channels line up. As a work around you can try using kms keys as intermediate step. -us/windows-server/get-started/kmsclientkeys#windows-server-2012-r2
I paid for server-2003/2008/2012/2016 and never got credit to use for an upgrade when it came time for 2016 to expire, I found you. I work for a nonprofit and sometimes the work is 24/7. They have no more money because of the state of the world and so many people in need. You just helped a lot of people. The cost of Win Server feeds many and provides meds. Thanks again.

OUR KMS host is W2012 R2 server and it has the patch KB3173424 and the latest security update KB4512488. I installed the Windows Srv 2019 DataCtr/Std KMS key on this host machine and it was successful. Now on my client which is a server 2019 std when I try to activate I get an error stating 0XC004F074 No KMS service could be contacted. This client can actually communicate to the host like I can telnet to KMS Host on port 1688 and then I have manually set the KMS host by using the slmgr.vbs /skms hostserver:1688 cmd.
KMS clients connect to a KMS server, also called the KMS host, on the network for activation. A KMS host can be a VM or physical machine. To activate a computer running Windows Server 2019, the KMS host must use one of the following OSes: Windows Server 2012 R2, Windows Server 2016 or Windows Server 2019. 2b1af7f3a8
