[how-to] Upload large files to S3

Hmm, still sounds like you have something set wrong in your bucket. I'll post some of my settings below, maybe that will help. I can't remember, but I may have had to enter different details than the documentation. This is what currently works for me:

my Bucket policy:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "PublicRead",
            "Effect": "Allow",
            "Principal": "*",
            "Action": [
                "s3:GetObject",
                "s3:GetObjectVersion"
            ],
            "Resource": "arn:aws:s3:::MyBucketChangeThisToYours/*"
        }
    ]
}

Cross-origin resource sharing (CORS):

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