502 Bad Gateway Error for Laravel site running on nginx

Most of my page works, but when I try to access part of my site I get a 502 Bad Gateway error.

I am running the latest version of Laravel, nginx and php5-fpm. My server is an AWS Ubuntu 14.04 instance.

I check the nginx log and get the following error

2016/07/01 19:06:29 [error] 1101#0: *8 recv() failed (104: Connection reset     by peer) while reading response header from upstream, client: [client IP here], server: [aws server IP here], request: "GET /get/request/here/build?active=talent HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "[server IP here]", referrer: "http://[server IP here]/admin?all=yes"

Here is my fpm/pool.d/www.conf file (everything that is not coded out more or less)

; Pool name
[www]

listen.owner = www-data
listen.group = www-data
;listen.mode = 0660

pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
;pm.process_idle_timeout = 10s;
; pm.max_requests = 500

chdir = /
catch_workers_output = yes

Here is my nginx/sites-available/default file:

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /var/www/laravelproject/public;
    index index.php index.html index.htm;

    server_name [server-ip-here];

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        try_files $uri /index.php =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

How can I fix this?
