AWS S3 Access Denied Error

I am getting access denied error when I try to open a file I have hosted on my S3 bucket.

When my Django app tries to get the same file I get 403 Forbidden Error on my console.

I am getting this when I open a link to a file.

<Error>
<Code>AccessDenied</Code>
<Message>Access Denied</Message>
<RequestId>D4FCD94BD9DEE9F8</RequestId>

</HostId>
</Error>

My CORS Configuration is this

<CORSConfiguration>
    <CORSRule>
        <AllowedOrigin>*</AllowedOrigin>
        <AllowedMethod>GET</AllowedMethod>
        <AllowedMethod>POST</AllowedMethod>
        <AllowedMethod>PUT</AllowedMethod>
        <MaxAgeSeconds>3000</MaxAgeSeconds>
        <AllowedHeader>Authorization</AllowedHeader>
    </CORSRule>
</CORSConfiguration>

What should I do so that my static files get served properly ?
