Amazon S3 Bucket Policy Public Access Denied

Question

I'm trying to make my S3 bucket public but when I add the following policy I get Error Access Denied:

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

Answer 1

Go in to your Bucket > Permissions > Public access settings > Edit > Untick Block new public ACLs and uploading public objects and Remove public access granted through public ACLs (warning)

Answer 2

AWS has introduced Amazon S3 Block Public Access – Another Layer of Protection for Your Accounts and Buckets | AWS News Blog.

You must now disable this feature on any buckets you wish to be publicly accessible.
