Local drive to S3 sync issue

[rodm]

I have configured it to do a S3 sync, from local to S3. Credentials and policies all look good. I can see the bucket in the S3 explorer in the profile. However, the sync never runs and it reports a 403 Forbidden. When I view the log I get:

>List Bucket.
>GET /
403 Forbidden
<Access Denied
>List Bucket.
>GET /
403 Forbidden
<Access Denied
>List Bucket.
>GET /
403 Forbidden
<Access Denied
>List Bucket.
>GET /
403 Forbidden
<Access Denied
>GET /?max-keys=1000&delimiter=/
<200 OK
<Get 2 folders.

The user policy is:

{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "Stmt1444776680000",
"Effect": "Allow",
"Action": [
"s3:*"
],
"Resource": [
"arn:aws:s3:::bucket",
"arn:aws:s3:::bucket/*"
]
}
]
}

The bucket policy is:

{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "PublicReadGetObject",
"Effect": "Allow",
"Principal": "*",
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::bucket/*"
}
]
}

Please advise
Thanks

I'm using BestSync to synchronize with Amazon S3 bucket without problem.
