404 Not Found nginx/1.14.2 after upgrade PHP 8 on Azure – Laravel – Phpmyadmin

I’m trying to upgrade from PHP 7.4 to PHP 8 on Azure App Service (Linux).

It shows the following error:
404 Not Found – nginx/1.14.2

I understood that the problem is that Azure from PHP 8 use NGINX instead Apache.
So I followed the steps given here:
https://azureossd.github.io/2021/09/02/php-8-rewrite-rule/index.html

For a while it’s worked correctly but from the day after it stopped to work and restart to show the error "404 Not Found
nginx/1.14.2"

This is my default file:

server {
    #proxy_cache cache;
    #proxy_cache_valid 200 1s;
    listen 8080;
    listen [::]:8080;

        index  index.php index.html index.htm hostingstart.html;
        try_files $uri $uri/ /index.php?$args;
    }
