Why does Chilkat Http experience handshake error at "https" but not at "http"?

Question

The "http" addresses worked fine. The "https" version gives me a handshake error:

This is the error that I get when I call the following:

Dim lSuccess&
lSuccess = nHttp.Download("https://autoconfig.thunderbird.net/v1.1/gmx.de", "d:\weg.xml") 

lSuccess returns 0 which mean an error occured.

You're using a VERY OLD version of Chilkat. Update Chilkat to the latest version.. TLS and TLS server requirements evolve over the years. One cannot expect any implementation to work forever when the external world is always changing..
