[1096] [fixed] How to configure nuxt.js using nginx and proxy

Hello everyone, I'm trying to put in nuxt for the first time in production. And when I put there the images, javascript and css files, are giving 404 error. I will pass my settings.

Ubuntu: 16.05 Nginx: last Nodejs: 6 Nuxt.js: last

Ngnix proxy file config

server {
       listen 80;
       listen [::]:80;

       server_name davidcosta.com.br www.davidcosta.com.br;

       location / {
               try_files $uri $uri/ =404;
                proxy_pass http://localhost:8080;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection 'upgrade';
                proxy_set_header Host $host;
                proxy_cache_bypass $http_upgrade;

       }
}
