Can't run Laravel app on digitalocean using ngnix - php

Question

My Laravel app is returning 404 on every route.
This is the address: http://67.205.191.11/, when I try for example http://67.205.191.11/classes, 404 not found is returned.
my nginx default config file looks as below:
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
root /var/www/venture-backend/public/;
index index.php index.html index.htm;
# Make site accessible from http://localhost/
server_name 67.205.191.11;
location / {
try_files $uri $uri/ /index.php$is_args$args;
}
# Only for nginx-naxsi used with nginx-naxsi-ui : process denied requests
#location /RequestDenied {
# proxy_pass http://127.0.0.1:8080;
#}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
#error_page 500 502 503 504 /50x.html;
#location = /50x.html {
# root /usr/share/nginx/html;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
try_files $uri /index.php =404;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
Anyone knows why my routes are not working?
