Terraform: AWS bucket

Hello I am doing a terraform course and I came across an error that I am not able to pass. I created a container in docker with terraform and it has the following files main.tf,ec2.tf,output.tf,variable.tf. I created an IAM on aws and gave the administrator access permission for it, inside the container export my key and secret key, also create a bucket on aws and ta how I publish the permissions of it. When inside the container I am giving the command terraform init so it is giving this error:

Initializing the backend... Error refreshing state: AllAccessDisabled: All access to this object has been disabled status code: 403, request id: 63C2B2B19AFF684C, host id: N33 / aFmFs5JfC3BZcWazaotlEjp+wKk5kfR3Pq1Kg7NG1soDv06wyJTK9Jbxkwajnd215ppku50 =

provider "aws" {
  region  = "us-east-2"
  version = "~> 2.0"
}

terraform {
  backend "s3" {
    # Lembre de trocar o bucket para o seu, não pode ser o mesmo nome
    bucket = "terraformgerson"
    key    = "terraform-test.tfstate"
    region = "us-east-2"
    encrypt = "true"
    dynamodb_table = "terraform-state-lock-dynamo"
  }
} 

The buccket I created on aws is named terraformgerson
