S3 configuration

Hello,

I'm trying to setup S3 for a new project and after following as much instructions as I could find the image attachment process still fails. When I try to add an image to a blog post, I select it from my local file system, the image appears for a moment in the perch UI and then just disappears. I understand that the upload to S3 fails. Could be permissions issue but can't be sure. And that's my question: Is there any place to look or any perch way to debug the problem?

<?php 
    return [
        'blogimages' => [
                 'type'      => 'amazon_s3',
                 'web_path'  => 'https://s3bucketname.s3.amazonaws.com',
                 'file_path' => 's3bucketname',
         ],
    ];
?>

I had a look at Amazon's troubleshooting guide and they suggest to check in dev tools. So I did and noticed no request to Amazon when I add images. I understand that the image is not even trying to leave Perch.

Any hint would be highly appreciated.
