ManagedBlockchain Copy cert file from S3 - failing

Question

Hi I am following the steps to Enroll a Admin User from here https://docs.aws.amazon.com/managed-blockchain/latest/hyperledger-fabric-dev/get-started-enroll-admin.html

The step to copy a preconfig'd cert from a S3 location to my EC2 fails with Forbidden.

I have checked my role for permissions, that is attached to the EC2. The perms look like this:

``{
            "Sid": "AccessManagedBlockchainBucket",
            "Effect": "Allow",
            "Action": [
                "s3:GetObject"
            ],
            "Resource": "arn:aws:s3:::us-east-1.managedblockchain/*"
  },``

I get this:

`[xxxx@ip-xxxxx~]$ aws s3 cp s3://us-east-1.managedblockchain/etc/managedblockchain-tls-chain.pem  /home/ec2-user/managedblockchain-tls-chain.pem
fatal error: An error occurred (403) when calling the HeadObject operation: Forbidden
`

Any pointers on what is wrong with the s3 cp still?

[This article](https://stackoverflow.com/questions/36144757/aws-cli-s3-a-client-error-403-occurred-when-calling-the-headobject-operation) suggests your policy may need to be adjusted.
