I’ve setup a server block file for a xenforo instance I’m setting up in /sites-available and symlinked to /sites-enabled…

All seems to be fine with that. Restarted Nginx and it’s still displaying the default .html page.

Is anything else needed?

Here is the server block file in /sites-available:

Default server configuration

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

    # SSL configuration
    #
    # listen 443 ssl default_server;
    # listen [::]:443 ssl default_server;
    #
    # Note: You should disable gzip for SSL traffic.
    # See: https://bugs.debian.org/773332
    #
    # Read up on ssl_ciphers to ensure a secure configuration.

    #
    # include snippets/snakeoil.conf;

    root /var/www/html/xf_pluix;

    # Add index.php to the list if you are using PHP
    index index.php index.html;

    server_name     pluix.com;

   location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            try_files $uri $uri/ /index.php?$uri&$args;
    }

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {
    #       include snippets/fastcgi-php.conf;
    #
    #       # With php7.0-cgi alone:
            fastcgi_pass 127.0.0.1:9000;
    #       # With php7.0-fpm:
    #       fastcgi_pass unix:/run/php/php7.0-fpm.sock;
            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;
    #}

}

Thanks for any and all help!
