Fine Uploader to S3 bucket getting 405 Method Not Allowed error
I have been banging my head against the wall on this and am entirely stumped. I am trying to use FineUploader to upload files directly to my Amazon S3 bucket. I have essentially copied the code from the fineuploader.com web page (Upload Files Directly to Amazon S3) and the server-side PHP.
When I attempt to upload a file I see the post to the signature endpoint seems to work successfully but when it attempts to upload to S3 I get a 405 "Method Not Allowed" error.

/**
* PHP Server-Side Example for Fine Uploader S3.
* Maintained by Widen Enterprises.
*
* Note: This is the exact server-side code used by the S3 example
* on fineuploader.com.
*
* This example:
* - handles both CORS and non-CORS environments
* - handles delete file requests for both DELETE and POST methods
* - Performs basic inspections on the policy documents and REST headers before signing them
* - Ensures again the file size does not exceed the max (after file is in S3)
* - signs policy documents (simple uploads) and REST requests
* (chunked/multipart uploads)
*
* Requirements:
* - PHP 5.3 or newer
* - Amazon PHP SDK (only if utilizing the AWS SDK for deleting files or otherwise examining them)
*
* If you need to install the AWS SDK, see http://docs.aws.amazon.com/aws-sdk-php-2/guide/latest/installation.html.

The software looks amazing but I just can't get past this. Any help is appreciated.
Answer
I'm guessing this is a DNS issue created when you mapped your custom domain name to your S3 bucket. After resolving upload.roughdrag.com, it looks like you have mapped this CNAME to "upload.roughdrag.com.s3-website-us-east-1.amazonaws.com". Try mapping that CNAME to "upload.roughdrag.com.s3.amazaonaws.com" instead.
Update 1:
If you are still seeing issues after this change, I would post in the AWS S3 forums. Hopefully an employee will answer. There may be an issue with your bucket/CNAME that I cannot see from my end. It looks like a POST request to upload.roughdrag.com.s3.amazonaws.com goes though, but there are issues sending a POST request to upload.roughdrag.com. I verified this with Postman.
Update 2:
With your latest CNAME change, it looks like POST requests are being accepted by S3.
