为什么 Chilkat Http 在 "https" 而不是 "http" 时出现握手错误？

Question

“http”地址工作正常。 “https”版本给我一个握手错误：

这是我在调用以下命令时遇到的错误：

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

lSuccess returns 0表示发生错误。

您使用的是非常旧的 Chilkat 版本。将 Chilkat 更新到最新版本。TLS 和 TLS 服务器要求多年来不断发展。当外部世界总是在变化时，不能指望任何实现永远有效..

为什么 Chilkat Http 在 "https" 而不是 "http" 时出现握手错误？

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