config setup for the wordpress file in sites-available

Sorry but I am having a little issue after following this guide. It seems to be coming from the config file that Nginx uses to locate WordPress

My current syntax is:

server {

    location = /favicon.ico { log_not_found off; access_log off; }
    location = /robots.txt { log_not_found off; access_log off; allow all; }
    location ~* \.(css|gif|ico|jpeg|jpg|js|png)$ {
        expires max;
        log_not_found off;
    }
    


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

I am using a Linux mint 19 system (runs Ubuntu 18.04), and all things related to the LEMP stack are well set, and I am hosting on my laptop’s localhost but when I enter ‘localhost’ in browser I get a 403 error.

Seems there is no file for Nginx to process, please help me get through this issue.
