Git Push Errors: When Neither SSH nor HTTPS Works
You've been working hard on your project, making changes, and now you're ready to push them to your remote repository. But instead of a smooth push, you're greeted with a wall of error messages – and it's happening whether you use SSH or HTTPS! This can be incredibly frustrating, but fear not, we're here to help you navigate these common Git push error scenarios.
Understanding the Problem
The root cause of this issue can vary, but the core message is the same: Git can't push your changes to the remote repository. This could be due to:
- Network issues: The connection between your computer and the remote repository might be unstable or blocked.
- Authentication problems: Your credentials (SSH keys or username/password) might be incorrect or invalid.
- Remote repository changes: Someone else might have pushed changes to the repository, creating a conflict that needs to be resolved before you can push.
- Local repository issues: There might be problems with your local repository's configuration, making it impossible to synchronize with the remote.
- Git version conflicts: Your local Git version might not be compatible with the remote repository's version.
Scenario and Code Examples
Imagine you're working on a project hosted on GitHub. You make some changes to your code, add them to the staging area, commit them, and then try to push them using both SSH and HTTPS:
SSH Push Attempt:
git push origin main
Output:
fatal: unable to access 'https://github.com/username/project.git/': The requested URL returned error: 403
HTTPS Push Attempt:
git push origin main
Output:
remote: Permission to username/project.git denied to user.
fatal: unable to access '[email protected]:username/project.git/': The requested URL returned error: 403
Troubleshooting Strategies
1. Check Your Network Connection:
- Internet connectivity: Ensure you have a stable internet connection.
- Firewall/VPN: If you're using a firewall or VPN, check if they are interfering with your Git operations. Try disabling them temporarily to see if it resolves the issue.
2. Verify Credentials:
- SSH Keys: If using SSH, make sure your SSH key is correctly configured and added to your GitHub account.
- Username/Password: If using HTTPS, double-check your GitHub username and password for accuracy.
- Two-Factor Authentication (2FA): If you have 2FA enabled, ensure you're providing the correct code along with your username/password.
3. Resolve Remote Repository Conflicts:
- Pull Changes: Fetch and merge the latest changes from the remote repository using
git pull origin main. - Resolve Conflicts: If you encounter merge conflicts, manually resolve them using your code editor.
4. Inspect Your Local Repository:
- Untracked Files: Ensure there are no untracked files that might cause problems. Use
git statusto check for them. - Branch Mismatch: Verify you are on the correct branch. Use
git branchto see your current branch andgit checkout mainto switch to the desired branch.
5. Git Version Compatibility:
- Upgrade Git: If your Git version is outdated, consider upgrading to the latest version.
Additional Tips and Resources
- GitHub Help: GitHub provides extensive documentation and troubleshooting guides.
- Stack Overflow: Search for similar error messages on Stack Overflow to find solutions from other developers.

Remember: The exact solution will depend on the specific error message and your setup. Carefully analyze the error messages, troubleshoot the possible causes, and refer to the resources above for guidance.
By following these steps, you can effectively troubleshoot Git push errors and get your code flowing smoothly to your remote repository. Happy coding!
