nginx - php artisan serve runs at 8000 and accesses 502 error

Run php artisan serve in the virtual machine (192.168.73.130)
Laravel development server started on http://localhost:8000/
Visit http://192.168.73.130:8000
Result: ERR_CONNECTION_REFUSED

So configure a forwarding in the virtual machine nginx:

<code>server {
                listen 0.0.0.0:80;
                server_name lara.com;

        location / {
                proxy_set_header Host $http_host;
                proxy_set_header X-NginX-Proxy true;
                proxy_set_header X-Real-IP $remote_addr;

                proxy_pass http://localhost:8000;
                #proxy_buffering off;
                proxy_redirect on;
                }
        }
</code>

When accessing lara.com in the local browser, it shows 502 Bad Gateway
If you go to curl http://localhost:8000/ in the shell, there will be HTML returned
Is my nginx configuration wrong?
Please solve (Laravel’s environment is very troublesome) ! ! )
