Virtual Host config for Nginx as Proxy

I’m having a problem with Virtual Host on nginx as proxy for ubuntu. My website is been redirected from example.com to www.example.com/index.php Also, my htaccess is not working. Someone could help me? Thanks.

server {
    listen 80;
    server_name test.io www.test.io;
    root /var/www/test.io;
    index index.php index.htm index.html;

    location / {
        try_files $uri $uri/ /index.php;
    }

    location ~ \.php$ {
        proxy_pass http://your_ip_address:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    location ~ /\. {
        deny all;
    }
}
