## 问题 ##

换了个wifi，git clone拉取代码就会报错，切回原来的wifi，又是可以的，反复尝试，最终确认，这个特定的wifi下，网页和命令行都不能访问github，甚是神奇。

G:\mylearn\source-code>git pull
    ssh: connect to host github.com port 22: Connection timed out
    fatal: Could not read from remote repository.
    
    Please make sure you have the correct access rights
    and the repository exists.
    
    G:\mylearn\source-code>ssh -T git@github.com
    ssh: connect to host github.com port 22: Connection timed out

## 解决方案： ##

在C:\\Users\\wangzx.ssh目录下，也就是放这个的目录下：  
![在这里插入图片描述][20201013141648658.png]  
创建一个文件，config，不需要后缀名，内容为：

Host github.com
    User xxxyouremail@qq.com
    Hostname ssh.github.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa
    Port 443

添加完后如下：
