아래와 같이 오류가 떴을 때,

Authentication failed. Some common reasons include:

- You are not logged in to your account: see File > Options.
- You may need to log out and log back in to refresh your token.
- You do not have permission to access this repository.
- The repository is archived on GitHub. Check the repository settings to confirm you are still permitted to push commits.
- If you use SSH authentication, check that your key is added to the ssh-agent and associated with your account.
- If you use SSH authentication, ensure the host key verification passes for your repository hosting service.
- If you used username / password authentication, you might need to use a Personal Access Token instead of your account password. Check the documentation of your repository hosting service.
