AWS: S3 Bucket AWS You can't grant public access because Block public access settings are turned on for this account

Question

I want to make S3 bucket public to everyone but I get access denied when I do That and it Says

You can't grant public access because Block public access settings 
are turned on for this account. To determine which settings are 
turned on, check your Block public access settings.

When I go to public access settings everything is turned off.

I did set IAM User and User has AmazonS3FullAccess policy

{
"Version": "2012-10-17",
"Statement": [
    {
        "Effect": "Allow",
        "Action": "s3:*",
        "Resource": "*"
    }
  ]
 }

I did set policy on the bucket

{
"Version": "2012-10-17",
"Id": "Policy1557294263403",
"Statement": [
    {
        "Sid": "Stmt1557294241958",
        "Effect": "Allow",
        "Principal": {
            "AWS": "arn:aws:iam::726051891502:user/borroup-admin"
        },
        "Action": "s3:*",
        "Resource": [
            "arn:aws:s3:::borroup",
            "arn:aws:s3:::borroup/*"
        ]
      }
    ]
 }

I did set CORS configuration editor on the bucket

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<CORSRule>
<AllowedOrigin>*</AllowedOrigin>
<AllowedMethod>GET</AllowedMethod>
<AllowedMethod>POST</AllowedMethod>
<AllowedMethod>PUT</AllowedMethod>
<MaxAgeSeconds>3000</MaxAgeSeconds>
<AllowedHeader>Authorization</AllowedHeader>
</CORSRule>
</CORSConfiguration>

have you succeed ? – Tilefish

@Tilefish Yes I did the Answer with screenshot below it got to work – Manual

Answer 1

It seems like it has to be unchecked from both places Permissions and Block public access (account settings).

Manual

I think that the one on the left is for default values, while the tab in the bucket is for that specific bucket. – Southsoutheast

Is it just me or is this the worst part of AWS? Why can you not have block public access and then create a bucket policy to finer grain internal account permissions? – Aklog

What does it mean public? is an account I have in aws is public? becuase using this feature blocks it. This doesn't make sense to block all accounts from accessing the bucket. – Waksman

Answer 2

I hope you have sorted this out already, if not go to Edit public access settings

then type confirm in the next screen to go ahead with the change

Answer 3

I had this same challenge when working on a Rails project where I was using AWS S3 bucket for storing images.

Here's how I solved it:

1. Click and open the bucket where the assets/images/files you want reside.

2. Click on the Permissions tab at the top menu of the bucket page

3. Click on Edit in the Block public access (bucket settings) section. And then untick Block all public access. Then save your changes.

Note: You can select the kind of public access that you want from the options given.

That's all.

I hope this helps

Answer 4

In addition to walterc's answer, if anyone is still having problems I had to click into the specific file I wanted access to and click "Make Public" for that file as well since just Making the bucket public won't work for specific file link access.

Answer 5

Go to your bucket and click on the permission tab and unticket Block public access (bucket settings) from both place.
