Git Clone : Unknown SSL protocol error in connection to github.com:443
提问by Ankur
I am trying to clone a GitHub project in my office system.
我正在尝试在我的办公系统中克隆一个 GitHub 项目。
set HTTPS_PROXY=http://<UN>:<PWD>@<PROXYSERVER>:<PORT>
set HTTP_PROXY=http://<UN>:<PWD>@<PROXYSERVER>:<PORT>
I have set HTTPS and HTTP proxies also set sslVerify to false
我已经设置了 HTTPS 和 HTTP 代理也将 sslVerify 设置为 false
[https]
sslVerify = false
[http]
sslVerify = false
still, I am getting "Unknown SSL protocol error in connection to github.com:443".
尽管如此，我还是收到“与 github.com:443 相关的未知 SSL 协议错误”。
Can someone advise me what do I need to do?
有人可以告诉我我需要做什么吗？

Make sure to use the latest Git (2.12.2) to check if the issue persists.
确保使用最新的 Git (2.12.2) 检查问题是否仍然存在。
If it does, see the various settings I mention in "Unknown SSL protocol error in connection" in order to debug this:
如果是这样，请查看我在“连接中的未知 SSL 协议错误”中提到的各种设置，以便调试：
# Windows
set GIT_CURL_VERBOSE=1
set GIT_TRACE_PACKET=2
# Unix
export GIT_CURL_VERBOSE=1
export GIT_TRACE_PACKET=2
Update Feb. 2018: after issue 587(Disable TLSv1.0 and Disable Cipher), this is finally in place: no more TLSv1.0.
See "Discontinue support for weak cryptographic standards", updated in 2018 with "Weak cryptographic standards removal notice".
2018 年 2 月更新：在问题 587（禁用 TLSv1.0 和禁用密码）之后，这终于到位：不再有 TLSv1.0。
请参阅“停止支持弱密码标准”，2018 年更新为“弱密码标准删除通知”。
On February 8, 2018 we'll start disabling the following:
- TLSv1/TLSv1.1: This applies to all HTTPS connections, including web, API, and git connections to https://github.comand https://api.github.com.
- diffie-hellman-group1-sha1: This applies to all SSH connections to github.com
- diffie-hellman-group14-sha1: This applies to all SSH connections to github.com
从 2018 年 2 月 8 日起，我们将开始禁用以下功能：
- TLSv1/TLSv1.1：这适用于所有 HTTPS 连接，包括 web、API 和到https://github.com和https://api.github.com 的git 连接。
- diffie-hellman-group1-sha1：这适用于到 github.com 的所有 SSH 连接
- diffie-hellman-group14-sha1：这适用于到 github.com 的所有 SSH 连接
So make sure your:
因此，请确保您的：
- Git Credential Manager is greater than 1.14.0
- Git on RedHat is (for RedHart) in 7.2 or more
- JDK is 8 or more.
- Git Credential Manager 大于 1.14.0
- RedHat 上的 Git（对于 RedHart）是 7.2 或更高版本
- JDK 为 8 或更多。

Make sure your proxy is set correctly if you have one: git config --global http.proxy http://User:PASSWORD@PROXY:PORT
如果您有代理，请确保您的代理设置正确： git config --global http.proxy http://User:PASSWORD@PROXY:PORT
