Is TLS1.3 supoorted? (via Winhttp)

Hi,
I upgrade my MFC app from VC2017 to VC2019, use WINSDK (10.0.19041.0)
Platform : Win10 1903

I had try to connect to server with TLS1.3, but failed.

Use IE 11 (TLS1.3 enabled in advanced setting) failed to , but MS Edge connect OK.

This Win10 1903 version is supported TLS 1.3 using Winhttp??

Any register key need to be added?

Hi @JojoTang-3993,

TLS 1.3 is not yet supported in Windows 10 version 1903, it will be supported in later versions of Windows 10 or Windows 11.

TLS protocol version support
