how to run two laravel project on same ip

I have a vps server with an Ubuntu 20.4 OS.I have two Laravel projects at these paths:

first app:

/var/www/html/public/index.php

second app:

/var/www/hampa/html/public/index.php

my default nginx config:

/etc/nginx/sites-available# cat defaultserver {    listen 80;    server_name localhost;    root /var/www/html/public;    index index.php index.html index.htm;    charset utf-8;    client_max_body_size 100M;    location /hampa {        alias /var/www/hampa/html/public;        index index.php index.html;        try_files $uri $uri/ /hampa/public/index.php?$query_string;    }   location / {        try_files $uri $uri/ /index.php?$query_string;    }    location = /favicon.ico { access_log off; log_not_found off; }    location = /robots.txt  { access_log off; log_not_found off; }    error_page 404 /index.php;    location ~ \.php$ {        include snippets/fastcgi-php.conf;        fastcgi_pass unix:/var/run/php/php8.1-fpm.sock;        fastcgi_param SCRIPT_FILENAME $request_filename;        include fastcgi_params;    }    location ~ /\.(?!well-known).* {        deny all;    }}

but when I entered my IP and hampa project I got 404 error not found.All requests are redirected first project and I get a 404 error not found for the first project.
