TLS1.3 on Windows 2012 R2

Question

Hi,

TLS 1.3 is not supported in Windows 2012 R2 by default as per the link below.

https://learn.microsoft.com/en-us/windows/win32/secauthn/protocols-in-tls-ssl--schannel-ssp-

But, is there a workaround to have it enabled? One of the API we consume if going to support only TLS1.3 shortly and we don't have much time to upgrade the server.

Thanks

Hello @kumar-4478

Welcome to Microsoft Q&A Platform,

Windows Server 2012r2 does not support TLS 1.3, you must upgrade to Windows Server 2022 if you want to use it:

I hope this helps!
