ssh：连接到主机 gist.github.com 端口 22：操作超时致命：无法从远程存储库读取
ssh: connect to host gist.github.com port 22: Operation timed out fatal: Could not read from remote repository
我正在尝试将一些代码推送到要点。我知道还有很多其他人也有类似的问题，我已经查看了所有我能找到的其他帖子，但他们似乎没有解决我的问题。
➜ streamgraph git:(master) git push
ssh: connect to host gist.github.com port 22: Operation timed out
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
大多数人认为这是 ssh 的问题。但是，我经历了一个漫长的过程来确保我的 ssh 密钥已更新，并且在测试 ssh 时收到此消息，据我所知，这意味着我的 ssh 设置没有问题。
➜ streamgraph git:(master) ssh -T git@github.com
Hi adrianturcato! You've successfully authenticated, but GitHub does not provide shell access.
最后一点，git 命令在当天早些时候工作，然后突然停止工作。也有一段时间我 运行 git 命令不起作用，然后我再次 运行 它会起作用。但现在在过去的 24 小时里，它一直不起作用。
这是互联网连接问题还是 git 集线器服务器问题？

使用 https:// 协议。
所以这似乎实际上是 gits SSH gist 服务器的错误。
虽然这有效：
streamgraph git:(master) ssh -T git@github.com
Hi adrianturcato! You've successfully authenticated, but GitHub does not provide shell access.
这次超时：
streamgraph git:(master) ssh -T git@gist.github.com
我是如何解决这个问题的：
我更改了终端中的 git 配置文件以强制它使用 HTTPS：
git config --global url."https://gist.github.com/".insteadOf git@gist.github.com
git config --global url."https://".insteadOf git://
您可以随时更改此设置：
git config --global --edit
但由于我的 github 有 2fa，这仍然无法正常工作。所以我创建了另一个 github 帐户，我将暂时使用它。
