Nginx proxy subdomain to laravel url

Question

I'm trying to reverse proxy using nginx from subdomain to url served by Laravel (version 5.2). In my top domain (domain.com) it's served on url domain.com/sub . I want it accesible by domain sub.domain.com . It should proxy sub.domain.com to serve same thing with domain.com/sub . Here's my nginx conf for reverse proxy

server {
    listen 80;
    server_name sub.domain.com;

    location / {
        proxy_set_header   X-Real-IP $remote_addr;
        proxy_set_header   Host      $http_host;
        proxy_pass         http://domain.com/sub;
    }
}

Here's my nginx conf for laravel app

server {
    listen 80;
    listen [::]:80;

    # Useful logs for debug.
    access_log      /var/www/domain/access.log;
    error_log       /var/www/domain/error.log;
    rewrite_log     on;

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

    server_name domain.com local.domain;

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

But it returned 500 internal server error . Any suggestion to fix it or how to achieve that? Thanks :)

I've found it's problem and solution from here Nginx reverse proxy causing infinite loop

Looks like I set proxy_header host, thats what created loop. So I commented proxy_header host. Here's my full conf

server {
    listen 80;
    server_name sub.domain.com;

    location / {
        proxy_set_header   X-Real-IP $remote_addr;
        proxy_pass         http://domain.com/sub;
    }
}
