ssh: connect to host github.com port 22: Operation timed out

Last updated at Posted at 2019-11-24

SSH接続エラー?

普段からGitHubにアクセスしているMacでコードをアップしようとすると、22番ポートでSSH接続できないとのエラーがでたので対処していく。

$ git push -u origin HEAD
ssh: connect to host github.com port 22: Operation timed out
fatal: Could not read from remote repository.

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

結論

443番ポートでアクセスする設定で接続することで、接続に成功した。22番ポートで接続できなくなった理由は不明のまま。

$ vi ~/.ssh/config
Host github.com
    User git
    Hostname ssh.github.com
    Port 443
    IdentityFile ~/.ssh/id_rsa
$ git push -u origin HEAD
