## Common questions

### Does MinIO Client support S3-compatible storage with AWS Signature v2 and v4?

Yes, MinIO Client supports filesystems and Amazon S3 compatible cloud storage service using AWS Signature v2 and v4.

### What MinIO storage-path setup mistake can prevent the server from starting?

Start with one path instead of the 12-drive form. The 12-drive form expects 12 separate folders or drives, and missing folders can make the server fail to start.

### Which ports must be open if MinIO FTP or SFTP is enabled?

Allow ports 8021 and 8022. You should also allow the FTP passive range 30000-40000.

### What should I check if a self-hosted S3 endpoint is not accessible?

Check the S3 endpoint, TLS configuration, bucket access policies, and common connectivity errors.
