hello Guys,
I am trying to upload a photo on S3 Amazon by the course LiveView of the PragProg.
And I am having some errors.
on the application tells it complains for:
“External client failure”.

And on my console it complains for:

Access to XMLHttpRequest at 'https://<mybucket>.s3.amazonaws.com/' (redirected from 'http://<mybucket>.s3.amazonaws.com/') from origin 'http://www.localhost:4000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

and other error:

uploaders.js:21 POST https://<mybucket>.s3.amazonaws.com/ net::ERR_FAILED

In my configuration CORS I put:

[
    {
        "AllowedHeaders": [
            "*"
        ],
        "AllowedMethods": [
            "GET",
            "PUT",
            "POST",
            "DELETE",
            "HEAD"
        ],
        "AllowedOrigins": [
            "*"
        ],
        "ExposeHeaders": []
    }
]

I am trying to change the configuration on permissions but it’s not working.
Can anyone help me with this, please?
