Common Issues

Below you will find a list of common issues reported by our customers that you may find useful in troubleshooting a problem.

Copying certain files causes a prompt specifying "The file XXX has properties that can't be copied to the new location"

The virtual drive created by S3 Drive is of type exFAT. Certain NTFS specific functionality such as alternate data streams are not currently supported and may result in the warning above. Choosing to proceed with the operation when prompted by Windows is safe and does not affect the file content.

Does regularly clearing the cache improve upload and download speeds?

The S3 Drive cache does not behave like the cache in a web browser, and "clearing the cache" is not something that will help with transfer speeds. S3 Drive manages the cache for you, so you should never need to perform maintenance on the cache to keep it working efficiently. Slow transfer rates could stem from environmental factors outside of S3 Drive. See Caching Information for more details.

S3 connection failed: Connection failed: No connection could be made because the target machine actively refused it.

A connection refused error indicates a TCP-reset flag was received when the connection was initiated. This can mean no process is listening on the specified port, the port is being blocked by a firewall, or the IP address is incorrect.

S3 connection failed: Timeout.

A timeout error is thrown when the remote host does not respond after the specified amount of time in the Settings tab. It could indicate a firewall, antivirus, or proxy is dropping the connection.

S3 connection failed: Could not bind to LocalAddress.

A bind error indicates the application was not able to bind to the default networking interface. This can happen if the machine has multiple networking interfaces. To resolve the issue, set the LocalHost value of the Advanced Settings to the IP address of your default network interface.
