ssh: connect to host github.com port 22: Connection refused fatal: Could not read from remote 报错解决

问题描述：

git push 或 git pull 到 github项目，遇到如下报错，

ssh: connect to host github.com port 22: Connection refused
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

解决办法：

在SSH配置文件中，设置github的主机名为 ssh.github.com 设置443端口

vim ~/.ssh/config

复制如下代码到config文件

Host github.com
  Hostname ssh.github.com
  Port 443

保存退出后，运行git pull ，提示Please type ‘yes’, ‘no’ or the fingerprint: ，输入yes，大功告成！
