How to fix 404 not found nginx/1.21.6 problem?

Note that I put this file in this path after editing it etc/nginx/sites-enabled/book.conf

server { listen 90 ; listen [::]:90 ;

server_name localhost:8300;

location /(assets/|images/|img/|javascript/|js/|css/|stylesheets/|flash/|media/|static/|robots.txt|humans.txt|favicon.ico) {
root /books/public; #this is where my static files reside
access_log off;
expires 24h;

location / {
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_redirect off;
    proxy_pass http://localhost:8300;
    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;

    try_files $uri $uri/ /index.php?q=$uri&$args;

Otherwise, if you do not specify the port after your hostname, the default Nginx server block would be loaded.

Besides, that I could also suggest taking a look at the following tutorial on how to troubleshoot common Nginx problems:
