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

1. 改为 https 方式

私有仓库报错：remote 地址设置错误
私有仓库 remote 应该设置为：https

2. 修改配置信息，使用 ssh 443端口

$ git clone git@github.com:xxxxx/xxxx.git my-awesome-proj
Cloning into 'my-awesome-proj'...
ssh: connect to host github.com port 22: Connection timed out
fatal: Could not read from remote repository.

$ # This should also timeout
$ ssh -T git@github.com
ssh: connect to host github.com port 22: Connection timed out

$ # but this might work
$ ssh -T -p 443 git@ssh.github.com
Hi xxxx! You've successfully authenticated, but GitHub does not provide shell access.
$ # Override SSH settings
$ vim ~/.ssh/config

Add section below to it

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

$ ssh -T git@github.com
Hi xxxxx! You've successfully authenticated, but GitHub does not
provide shell access.
