Server 2022 KMS host key bug; Can't activate Win10 Enterprise LTSB/LTSC

We recently dropped our new Server 2022 KMS host key onto our KMS server. After the necessary update to accept the 2022 key and activating the new 2022 host key, we were able to activate our most com...

Update as of today contained two points:

1) Fix will be release for Server 2016 in week 2 of March 2022, and Server 2019 in week 3 of February 2022.

2) Microsoft has no reports of this behavior on a Server 2022 KMS host + 2022 key. (So either no one has spun up a new enough host to report this yet on anything other than a downlevel OS, or perhaps Server 2022 isn't affected)

I think I'm at the point where I'm going to snapshot my KMS host, upgrade to Server 2022, and see what happens.

Thanks for the update. I am definitely interested in the outcome of the OS upgrade as I'd likely do the same. I can't believe this issue won't be resolved for 2019 hosts until February!

i can confirm this also affects Server 2022, too.
We inplace upgraded our KMS-Server to 2022, since then it's not able to activate LTSC/LTSB Versions of Windows 10 any more.

  Same result in my test. Server 2022 KMS host with a 2022 key fixed nothing.
  
  Also just checked an LTSC 2021 client after launch today, it is affected by this bug too just like 2016 LTSB and LTSC 2019.

    ajc196 LTSC 2021 still use LTSC 2019 KMS infrastructure and keys
    
    the issue is fixed in Dev Insider Preview builds since 22478
    i don't know why it takes them so long to backport the fix to Servers 2022/2019/2016
