rclone: Failed to get endpoints with Amazon Cloud Drive

Hi,

I managed to install and configure the app, but after the initial token expires (in one hour), rclone is not able to refresh the token. The error message I get is:

root@www:~# rclone ls Default:
2016/04/08 19:45:36 Failed to create file system for "Default:": Failed to get endpoints: Get https://drive.amazonaws.com/drive/v1/account/endpoint: oauth2: cannot fetch token: 400 Bad Request
Response: {"error_description":"The request has an invalid grant parameter : refresh_token","error":"invalid_grant"}

I run the command as root, so it’s probably not a permission issue.

Details:

• Rclone version: rclone v1.28
• OS: Ubuntu 14.04.4 LTS (x64)
• Storage system: Amazon Cloud Drive
