Hello, I have recently deployed my Ruby on Rails application to a plain Ubuntu 16.04 droplet with Nginx, passenger & Let's encrypt.

The rails app worked fine without Let's encrypt but as soon as I installed it, I can't seem to understand why it's pointing to the "Welcome to Nginx" page instead of my rails app.

In /etc/nginx/sites-enabled/default I've used:

root /var/www/myapp;
root /var/www/myapp/code;
root /var/www/myapp/code/public;

This is where my application is.

Under /etc/nginx/nginx.conf I've tried using these:

user www-data;
user rails;
user root;

And I've even changed the ownership around a few times for root, rails and www-data:

sudo chown -R www-data:www-data /var/www/myapp
sudo find /var/www/myapp -type d -exec chmod 770 {} \;
sudo find /var/www/myapp -type f -exec chmod 660 {} \;

I don't know what gives... I keep getting "403 Forbidden nginx/1.14.0" but it worked fine and launched my deployed app without Let's Encrypt.

I would love some help, thank you!
