首先，是的，这是错误关闭问题的完全重复。
我有与原始海报完全相同的问题（就像他一样，除了他之外，我找不到其他人有这个问题）。
我已经为这个问题苦苦挣扎了一个多月，甚至不得不求助于使用 bitbucket（效果很好），即使我在 GitHub 上有付费计划，所以请耐心等待。不，这与维护无关（目前在https://status.github.com/上一切正常，我仍然遇到与 Vulpo 相同的错误）。
我的用户名和密码都不包含特殊字符。
我也可以使用其他计算机正常推送，所以是的，这一定与我的计算机有关。我正在运行 Arch Linux，这是我的git config -l：

启动一个新的 git 文件夹并只推送一个 README 文件可以正常工作，但是一旦我尝试推送我的文件，它就会挂起一段时间，然后返回一个错误：

Everything up-to-date
即使它说everything up-to-date，也没有任何东西被推送到远程服务器。
SSH 也不起作用。这是的输出ssh -v git@github.com：

在尝试使用 github.com 网站时，我也遇到了一些问题：我也无法使用该网站创建新的存储库；存储库名称检查需要很长时间，一段时间后会显示没有消息的红色警告。有时浏览 repos 需要很长时间，有时甚至无法加载主网站。如果我尝试使用 Chrome 的隐身窗口（如没有 cookie/缓存）浏览网站，它会在一段时间内完美运行（！！！），几分钟后会再次停止运行。这很奇怪。我可以正常使用所有其他网站（例如，也可以推送到托管在 bitbucket 中的其他 git repos）。
我尝试暂时禁用iptables，但这并没有解决任何问题。
编辑：它在 Windows 7 上运行良好。这只发生在 Arch Linux 上:(
因此，由于我无法重新打开该问题，是否有人知道这里可能发生了什么，以便我们可以删除我的问题并回答 Vulpo 的问题？谢谢！
