Connection reset by peer while reading response header from upstream (NGINX) - php

Question

Im trying to run the local project (php phalcon) using nginx on macOS but it seems nginx can't load the project correctly.
Here is my nginx log given :
2023/01/12 11:38:04 [error] 6170#0: *1 kevent() reported about an closed connection (54: Connection reset by peer) while reading response header from upstream, client: 127.0.0.1, server: bahana.front, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9074", host: "127.0.0.1:7002"
2023/01/12 11:38:05 [error] 6170#0: *1 kevent() reported about an closed connection (54: Connection reset by peer) while reading response header from upstream, client: 127.0.0.1, server: bahana.front, request: "GET /favicon.ico HTTP/1.1", upstream: "fastcgi://127.0.0.1:9074", host: "127.0.0.1:7002", referrer: "http://127.0.0.1:7002/"
and here is my site nginx config : (for loading the php phalcon project)
server {
listen 7002;
root /Applications/XAMPP/xamppfiles/htdocs/bahana-front/bahana/public;
index index.php;
server_name bahana.front;
location / {
try_files $uri $uri/ /index.php;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_pass 127.0.0.1:9074;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
also the php-fpm work well in the background (port 9074) :
So, what did i miss for the configuration, im little stuck and keep getting closed connection at nginx log and HTTP Error 502 (Bad Gateway) when accessing the site at http://127.0.0.1:7002, Gonna need your help, thanks.
