I cannot recommend this addon, whenever we have it enabled our store fails to load, we get "recv() failed (104: Connection reset by peer) while reading response header from upstream" error in our nginx error log.

This module simply replaces where certain files are read from - your CDN instead of the domain. Nothing else.
Please look into your server configuration first. A simple Google search can help with finding a solution. This is just one of the threads but there are more - https://serverfault.com/questions/543999/nginx-errors-recv-failed-104-connection-reset-by-peer-while-reading-respon/959426
Hope that helps.
