Permission denied to Rails when accessing app through https

Hello,

I am trying to get my Rails 4 working with SSL. I retrieved an SSL certificate from StartSSL.com and the installation on the server seems to have been successful.

However, I can’t get my app to work with https. It only works with http at this moment.

When I try to access it in the browser through https I am getting this error:

2014/06/04 18:05:56 [error] 23306#0: *3 “/home/rails/public/index.html” is forbidden (13: Permission denied), client: 23.251.149.69, server: myapp.com, request: “GET / HTTP/1.0”, host: “myapp.com”

This would be my NGINX configuration file in /etc/nginx/nginx.conf:

user www-data; worker_processes 4; pid /var/run/nginx.pid;

events { worker_connections 1024; }

http { sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; server_tokens off;

    server_names_hash_bucket_size 64;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    gzip on;
    gzip_disable "msie6";
    gzip_types text/plain text/xml text/css text/comma-separated-values;
    upstream app_server { server 127.0.0.1:8080 fail_timeout=0; }

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;

    server {
            listen 80;
            server_name myapp.com;
            rewrite ^ https://$server_name$request_uri? permanent;
    }

    server {
            listen 443;
            server_name myapp.com;
            root /home/rails/public;

            ssl on;
            ssl_certificate /etc/ssl/myapp.com.crt;
            ssl_certificate_key /etc/ssl/myapp.com.key;
    }

}

What am I missing here and how can this be fixed?
