当通过https代理使用时,git clone超时

通过https代理使用时,命令"git clone https://github.com/user/project.git "超时.

我以前成功地在代理后面运行了git,并且已经阅读了与git和代理使用相关的其他stackoverflow.现在我已经在我当前组织的主机上配置它以使用非身份验证代理,但它已超时.

代理是鱿鱼,非认证

通过TCP-443直接连接不是一个选项

我已经确认git正在联系代理

Git发出命令"CONNECT github.com:443 HTTP/1.1"

代理允许请求并在端口443上连接到github.com

libcurl验证github的证书并建立SSL连接(SSL_RSA_WITH_RC4_128_SHA)

git继续坐在那里,等待从未发生过的事情

超时发生

有谁之前经历过这个吗？有什么提示吗？

这是系统版本:

$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.4 (Santiago)

这是git版本和更新信息(RH中最新版本)

$ git --version
git version 1.7.11.3

$ sudo yum check-update git    
Loaded plugins: downloadonly, rhnplugin, security
This system is receiving updates from RHN Classic or RHN Satellite.

这是相关的环境变量:

$ export | grep http
declare -x http_proxy="http://proxy.hostname:3128/"
declare -x https_proxy="http://proxy.hostname:3128/"

这是我的.gitconfig(用于冗余):

$ cat ~/.gitconfig
[http]
        proxy = http://proxy.hostname:3128/
[https]
        proxy = http://proxy.hostname:3128/

这是一个git运行的例子(最终超时):

这是鱿鱼日志:

那么,这里发生了什么？有没有人有任何想法？
