sure, here it is:

nop, still nothing, I think there must be something else that is not nginx.
I went to this address:
https://wordpress.org/support/article/nginx/

and now it is working with these configuratins:

location = /favicon.ico {
            log_not_found off;
            access_log off;
    }

    location = /robots.txt {
            allow all;
            log_not_found off;
            access_log off;
    }

    location / {
            # This is cool because no php is touched for static content.
            # include the "?$args" part so non-default permalinks doesn't break when using query string
            try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
            #NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
            include fastcgi.conf;
            fastcgi_intercept_errors on;
            #fastcgi_pass php;
    }

    location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
            expires max;
            log_not_found off;
    }
