nginx default always returning 404 - nginx

Question

I cannot access my site anymore using the ip address (or domain name). It always 404 Not Found I use Laravel Forge with Digital Ocean with Ubuntu 14.04.
Here's my sites-enabled/default nginx file
# FORGE CONFIG (DOT NOT REMOVE!)
include forge-conf/default/before/*; #That directory is empty
server {
listen 80;
server_name default;
root /home/forge/default/public;
# FORGE SSL (DO NOT REMOVE!)
# ssl_certificate;
# ssl_certificate_key;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
index index.html index.htm index.php;
charset utf-8;
# FORGE CONFIG (DOT NOT REMOVE!)
include forge-conf/default/server/*; #That directory is empty
location / {
try_files $uri $uri/ /index.php?$query_string;
}
location = /favicon.ico { access_log off; log_not_found off; }
location = /robots.txt { access_log off; log_not_found off; }
access_log off;
error_log /var/log/nginx/default.log error;
error_page 404 /index.php;
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}
location ~ /\.ht {
deny all;
}
}
# FORGE CONFIG (DOT NOT REMOVE!)
include forge-conf/default/after/*; #That directory is empty
nginx.conf (Without commented lines)
user forge;
worker_processes auto;
pid /run/nginx.pid;
events {
worker_connections 768;
multi_accept on;
}
http {
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
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";
include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
On sudo service nginx restart my nginx/error.log only contains:
2016/03/24 15:25:07 [notice] 8416#0: signal process started
My nginx/default.log is empty.
Any clue of what I could look into?

It doesn't look like you defined the default server correctly - as per the Nginx docs, it should be
server {
listen 80 default_server;
server_name _; # This is just an invalid value which will never trigger on a real hostname.
...
}
Note the listen 80 default_server; in particular
