Possible causes:

1. Incorrect S3 endpoint/region configuration
2. Invalid AWS credentials or insufficient IAM permissions
3. Bucket doesn't exist or region mismatch
4. Network proxy/firewall intercepting requests

Please Verify:

• Verified CAP_AWS_ACCESS_KEY and CAP_AWS_SECRET_KEY are correct
• Confirmed bucket "capso" exists in the specified region
• Checked IAM permissions include s3:CreateMultipartUpload
• Verified S3 client region matches bucket region
