I've recently inherited a Rails app that uses S3 for storage of assets. I have transferred all assets to my S3 bucket with no issues. However, when I alter the app to point to the new bucket I get 403 Forbidden Status.

My S3 bucket is set up with the following settings:

• Permissions

  Everyone can list

• Bucket Policy

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

• CORS Configuration

  
  
      
          *
          GET
          3000
      
      
          https://www.appdomain.com
          PUT
          POST
          DELETE
          *
      
  
  

• Static Web Hosting

  Enabled.

What else can I do to allow the public to reach these assets?
