Nginx nodejs site static content - 404 error but works when access direct via ip

Question

I am trying to use nginx with my nodejs site, but i am having issues with the nginx configuration. Initially i couldn't get my css or images to display but i fixed that by adding:

location /images { root PATH_TO_MY_PROJECT_IMAGES_FOLDER }

However, i am having issues when it comes to visiting other pages on the site. I have a login system and when the user logs in the site takes them to "mydomainname.com/home", but when this happens i get a 404 error. In my nodejs code i send the user to home page by:

//should be logged in so show main search page
    app.get('/home', function(req, res) {
        if (req.session.user == null){
            // if user is not logged-in redirect back to login page //
            res.redirect('/');
        }   else{
            res.sendFile(path.join(__dirname + '/FrontEnd/home.html'));
        }
    });

My project is structure as follows:

ProjectNameFolder:
1. public
  1.1 FrontEnd
    1.1.1 login.html
    1.1.2 home.html
  1.2 Lots of other javascript files, some for front-end some for server

If i connect directly to my server via typing it's ip into the browser everything works perfectly, but i'm guessing that's bypassing nginx.

Nginx Config:

location /css {
  root /home/adam/NodeProject/public/FrontEnd/;
}
location /images {
  root /home/adam/NodeProject/public/FrontEnd/;
}
location / {
  try_files $uri $uri/ = 404;
  proxy_pass http://localhost:8888;
  .... other proxy stuff, like setting headers
}

Apologies, if this is a bit long winded, i have tried to provide as much clarity as i can.
