HttpClient Secure Protocol Error

#1 Post by rdonnay »

Has anyone used HttpClient with Https ?

I can connect to my https server with a web browser but not with HttpClient.

I'm using the same .PFX certificate with HttpClient as with HttpEndpoint.

I have tried all the 'secure-protocol' options available to the client to no avail.

ERROR_WINHTTP_SECURE_FAILURE is returned.

This might be TLS version related.

Is https server configured to TLS 1.3 only or it also allows older TLS 1.2 too ?
