-## Troubleshooting
-
-### Common Issues
-
-- **Permission denied**: Ensure you're running scripts with appropriate permissions (sudo for hardening scripts).
-- **Git not found**: Install git with your package manager (`apt install git`, `yum install git`, etc.).
-- **SSH connection lost**: The SSHD hardening script creates a backup at `/etc/ssh/sshd_config.bak` - you can restore it if needed.
-- **UFW conflicts**: If you have existing UFW rules, review them before running the Cloudflare script.
