Process Your Images Asynchronously
The Problem
I had the same thing happening to me. I found out that uploading large files were not the issue, it was the processing of the files after the upload by Paperclip that was the problem.
The browser has no problem keeping the connecting alive when it is actively uploading (or downloading) a file, but Paperclip was taking too long to process the files after they were uploaded, which the browser interprets as nothing happening. So if that processing takes too long (~1 min) the browser thinks something went wrong and returns an ERR_EMPTY_RESPONSE.
The Solution
I installed and implemented the wonderful delayed_paperclip gem, which pushes all the Paperclip processing to asynchronous tasks.
This means that once the files are uploaded, the request is completed and the browser gets an immediate response instead of waiting for Paperclip to process the files.
Problem solved.
