Question

第一次使用GitHub 在github.com上创建了存储库。现在我想推送到那个存储库。出现“连接失败”错误。

当我运行“ssh -Tv git@github.com”时，我会收到“connection timed out” 并且“ssh -T -p 443 git@ssh.github.com”失败并显示：Permission denied。

我关闭了Windows防火墙。同样的错误。

怎么办？如何连接到GitHub？
我正在使用VSCode。使用powershell命令行。

以下是我尝试过的命令：

    PS C:\gitsteve\maker> ssh -Tv git@github.com

如果出于任何原因阻止了SSH，请尝试切换到https网址

 cd /path/to/repo
 git remote set-url origin https://github.com/<username>/<reponame>.git

然后再试一次

 git push -u origin master

然后第一次，它应该需要您的GitHub用户名/密码（与您在私有SSH密钥上设置的密码无关：它需要您的GitHub帐户密码）

如果您安装了Git credential helper (as in this answer)，那么这些GitHub凭据将被缓存（这意味着vscode在下次推送时不会再次询问您的用户名/密码）
首先检查git config credential.helper的值：如果看到manager，则无需执行任何操作。

为什么错误从powershell命令行连接到github？
