I have a rails app that uses Font-Awesome. The icons are displaying in Development environment but not in production.

I have checked my Nginx/Passenger logs and these show the following:

`[21/Nov/2017:17:13:25 +0000] "GET /assets/back/font-awesome/fontawesome-webfont.ttf HTTP/1.1" 404 1564 "https://example.com/assets/application_back-b78b545bb6d96e3f98206780079663e7d84d11a41143a57b3ab7b110feac9944.css`

I have checked in the `public/assets/back/font-awesome/` directory and all the font files are showing like `fontawesome-webfont-aa58f33f239a0fb02f5c7a6c45c043d7a9ac9a093335806694ecd6d4edc0d6a8.ttf` which is why it cannot find the files but I don't know why it is doing this
