Typical Problems Troubleshooting

• Authentication failures: Check system time, API credentials, and two-factor settings.
• Mount issues: Ensure FUSE is installed (sudo apt-get install fuse) and user is in fuse group.
• Rate limiting: Shared IPs may hit API limits. Stagger large transfers or use chunking.
• Permission errors: Verify file ownership and permissions on mountpoints.
• Dependency conflicts: Use virtual environments for Python CLIs or containerize the tool.
• Slow transfer: Check network (MTU), proxy, and parallelism settings (rclone -P --transfers 4).
