我被困在防火墙后面，所以必须使用HTTPS访问我的GitHub存储库。我在Windows XP上使用cygwin 1.7.7。

我试过把遥控器设置为https://username@github.com/username/ExcelANT.git，但按下输入密码的提示，但输入后没有任何反应。 https://username:<密码>github.com/username/ExcelANT.git和克隆空回购从零开始，但每次它给我同样的错误

错误:SSL证书有问题，请检查CA证书是否正确。细节: SSL例程:SSL3_GET_SERVER_CERTIFICATE:访问https://github.com/username/ExcelANT.git/info/refs时证书验证失败

打开GIT_CURL_VERBOSE=1会给我

fatal: HTTP request failed

这是我的防火墙有问题吗，cygwin还是什么?

我没有在Git配置中设置HTTP代理，但是它是一个ISA服务器，需要NTLM身份验证，不是基本的，所以除非有人知道如何强制Git使用NTLM，否则我就完了。
