I already established a SSH connection, and did the AWS configuration. Now when I try to view the S3 buckets through the AWS CLI, the access denied error comes up. I had attached AmazonS3full access to the user through the root account. I have disabled the block ip address. I tried changing the region as well but still the error persists. So what do u suggest.

I was expecting that list of buckets will show as all the relevant permissions were granted but still nothing changed and the error is persisting.
