Amazon web services – Cannot upload image to AWS S3 from NextJS app – on server

I’ve got a problem with NextJS app. When I try to upload a file from localhost it works very well. The problem appears when I want to upload remotely. I host my app at Github Pages and when I what to do it I got 405 POST Error

I’ve checked the CORS

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

and bucket policy

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:*",
            "Resource": [
                "arn:aws:s3:::xxx",
                "arn:aws:s3:::xxx/*"
            ]
        }
    ]
}
