server {
    listen 80;
    server_name www.example.com example.com;

    location / {

        proxy_pass http://localhost:2000;
        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;
        proxy_set_header X-Forwarded-For $remote_addr;
    }
