ssh: connect to host github.com port 22: Connection timed out

昨天在使用VsCode向GitHub上传代码时，出现错误：（此前已经使用SSH的方式连接了GitHub仓库）

ssh: connect to host github.com port 22: Connection timed out
Please make sure you have the correct access rights
and the repository exists.

ssh: connect to host github.com port 22: Connection timed out
Please make sure you have the correct access rights
and the repository exists.

首先输入以下命令检查SSH是否能够连接成功（ssh后面有空格）

ssh -T [email protected]

发现报错：

ssh: connect to host github.com port 22: Connection timed out

端口连接超时。

查阅资料后，找到解决办法:

解决方案（亲测有效）

1. 在C盘——用户——你的主机名文件夹中找到.ssh文件夹；（此前配置SSH时会生成该文件夹）
2. 在.ssh文件夹中新建文件 config,不带后缀（可以新建文本文档，去掉.txt后缀）
3. 使用notepad++（或其他方式）打开config文件，输入以下内容，保存后即可

Host github.com
User YourEmail（你的邮箱）
Hostname ssh.github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
Port 443

4. 再次执行

ssh -T [email protected]

会出现以下提示，输入yes回车即可

The authenticity of host '[ssh.github.com]:443 ([192.30.255.123]:443)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '[ssh.github.com]:443,[192.30.255.123]:443' (RSA) to the list of known hosts.

再次执行ssh -T [email protected]，发现验证通过

Hi Clare! You've successfully authenticated, but GitHub does not provide shell access.

完成以上步骤后，再次上传代码到GitHub就不会报错了
