Network is unreachable error

[plitex]

Hello,

I'm trying to use this tool and after creating a file name s3sync.yml with my AWS credentials when I try to list my buckets I get this error:

user@ubuntu:~$ s3sync listbuckets

In your documentation there is no initial setup example, I'm missing something?

I have aws-sdk gem working to upload other single file backups on the same server.
