QA|Pycharm update时报错ssh: connect to host github.com port 22: Connection timed out|GIT

场景：

另一台电脑很久没有链接Github了，今天执行update失败，报错如下：

2023/9/20
15:09    Update failed
            Funny_Scripts and Spider: Connection reset by 20.205.243.166 port 22
            Could not read from remote repository.
            
            Please make sure you have the correct access rights
            and the repository exists.
            SoftTest: 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.

确认问题：

使用git bash执行ssh -T [email protected]，发现报错ssh: connect to host github.com port 22: Connection timed out

查资料解决：

1. 在C盘——用户——你的主机名文件夹中找到.ssh文件夹；（此前配置SSH时会生成该文件夹）
2. 在.ssh文件夹中新建文件 config,不带后缀（可以新建文本文档，去掉.txt后缀）
3. 打开config文件，输入以下内容，保存

Host github.com
User YourEmail（你的邮箱）
Hostname ssh.github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
Port 443

再次执行：ssh -T [email protected]

会出现以下提示，输入yes回车即可

The authenticity of host '[ssh.github.com]:443 ([192.30.255.123]:443)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '[ssh.github.com]:443,[192.30.255.123]:443' (RSA) to the list of known hosts.

　再次执行：ssh -T [email protected]，即可连上了

 此时在PYCHARM上执行update即可成功更新了

原因分析：

报错是ssh链接超时，而后面在config中重新定义了ssh所使用的端口，也就是说默认端口22被占用了，重新配置一个即可
