Common Issues and Troubleshooting

• Authentication fails: Ensure correct credentials and time synchronization (ntpd) on CentOS.
• Mount errors (FUSE): Install fuse and add your user to the fuse group.
• Connectivity problems: Check firewalls (firewalld) and proxy settings. Use curl or wget to test endpoints.
• Insufficient permissions: Run CLI commands with the appropriate user or sudo, and verify file ownership.
• Rate limits: Some services throttle API calls. Batch operations or add pauses in scripts.

Selecting the right CLI-supported cloud storage on CentOS depends on your security requirements, budget, and workflow. Whether you need end-to-end encryption, unlimited scalability, or seamless mounts, this guide equips you with the tools and examples to make an informed decision and streamline your automation.
