403 error for one of my server blocks

[nginxmike]

Hi, 

I installed nginx on an ubuntu server and then followed this tutorial (which
I'll quote from) to setup server blocks
https://digitalocean.com/community/articles/how-to-configure-single-and-multiple-wordpress-site-settings-with-nginx
.(I don't do any of the WordPress config in that article). It uses a
common.conf that the server blocks inherit from. 

In one of my server blocks, I setup a basic index.html page and set my
domain name for the server name in the server block file.

In the directory for my other server block, I setup a node app. That's the
one where I'm getting the 403 error.

Anyone know why this might be happening and how I might debug and/or fix
it?


server block

server {
    # URL: Correct way to redirect URL's
    server_name demo.com;
    rewrite ^/(.*)$ http://www.demo.com/$1 permanent;
}
server {
    server_name www.demo.com;
    root /home/demouser/sitedir;
    access_log /var/log/nginx/www.demo.com.access.log;
    error_log /var/log/nginx/www.demo.com.error.log;
    include global/common.conf;
}
