$ ssh -T [email protected] ssh: connect to host ssh.github.com port 22: Connection timed out

最近更新项目，发现push的时候出现:
Ssh: connect to host github.com port 22: Connection timed out
Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

然后输入ssh -T git@github.com出现：

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

解决方案：

1. 重新生成ssh：

ssh-****** -t rsa -C “你的邮箱”

2. 默认生成的key在：C:\Users\yourUserName.ssh中有3个文件：
   
3. github上配置key
   
4. $ ssh -T git@github.com验证连接：报错

Ssh: connect to host github.com port 22: Connection timed out
Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

5. 在ssh文件夹下添加config文件,内容如下:

Host github.com
User git
Hostname ssh.github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
Port 443

6. $ ssh -T git@github.com
