Laravel 4: 502 Bad Gateway with Nginx in only one view

I have a strange error on my server with nginx because I have been working on this project for many months and everything works fine except for only one view / page which I added because it shows me 502 Bad Gateway but I don't I understand why.

I already removed all the html of this view just to print plain text but the same
I've already removed all functionality from the controller just to render the view, but the same
I have already changed the route and controller name, but the same

I've tried a lot of things but the problem still persists and only this is displayed in the log of my server block:

Nginx server block error log

2015/08/05 08:25:42 [error] 2423#0: *885 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 187.189.190.62, server: stage.mywebsite.com, request: "GET /business/user/site.com/edit HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "stage.mywebsite.com", referrer: "http://stage.mywebsite.com/business"

Php-fpm error log

And that's all

Now I am going to show you my nginx configurations for the block and nginx.conf
