從 Gitlab 透過 ssh clone 發生錯誤 – port 22: Network is unreachable

git 要 pull 或 push 時都出現下列錯誤訊息

$ git clone [email protected]:user/projectName.git
Cloning into 'projectName'...
ssh: connect to host gitlab.hostname port 22: Network is unreachable
fatal: Could not read from remote repository.

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

解法

打開 ~/.ssh/config

加入以下資訊，存檔即可

Host gitlab.hostname
    HostName {host ip}
    User user
    Port 22
