I have setup a latest centos 8 on the server with nginx

and i am having a multiple projects will be running at server

For example :

var/www/html/project1

var/www/html/project2

var/www/html/project3

I have configured my NGINX.conf file as below

http {
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
    log_format scripts '$document_root$fastcgi_script_name > $request';

    access_log  /var/log/nginx/access.log  main;
    access_log /var/log/nginx/scripts.log scripts;

    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /var/www/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;
        index index.php index.html index.htm;

        location / {
            try_files $uri /index.html index.php;
        }

        location ~ \.php$ {
                try_files $uri /index.php =404;
                fastcgi_pass unix:/var/run/php-fpm/www.sock;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }
}

and server is running on the ipaddress so in server name i have just put _ as server name which will consider it localhost or ip.

But when i am running the projects

http://IPADDRESS/project1

http://IPADDRESS/project2

I am getting 404 Error and when i configured the script log. i found it going wrong as below

/var/log/nginx/scripts.log

/var/www/html/project1/public/404.html > GET /project1/ HTTP/1.1
/var/www/html/project2/public/404.html > GET /project2/ HTTP/1.1

Can please guide me where i am going wrong on NGINX configuration ?
