GitHub 异常------无法连接22端口：Connection timed out
问题描述
-
正常配置并使用使用
SSH方式，使用以下命令git clone、git pull、git push，报错如下：bashssh: 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.
原因分析：
- 表明
SSH连接在尝试通过22端口连接到远程服务器时超时。这可能是由于网络环境、防火墙设置或代理配置等原因导致的（很可能端口22被防火墙或提供商阻止了）。
解决方案：
bash
$ git clone [email protected]: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 [email protected]
ssh: connect to host github.com port 22: Connection timed out
$ # but this might work
$ ssh -T -p 443 [email protected]
