I am getting the following error on error log for my LEMP Ubuntu 20.04 setup on NGINX

704#704: *58 connect() failed (111: Connection refused) while connecting to upstream, client: xx.xx.xx.xx server: domain.tld, request: "GET /favicon.ico HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "domain.tld"

My domain configuration is as follows listed under /etc/nginx/conf.d/domain.conf

        server_name domain.tld;
        root /var/www/domain/;

        index index.html index.php;

        access_log /sites/domain/logs/access.log;
        error_log /sites/domain/logs/error.log;

        # Prevent access to certain file extensions
        location ~\.(ini|log|conf)$ {
                deny all;
        }

        # Enable WordPress Permananent Links
        location / {
                try_files $uri $uri/ /index.php?$args;
        }

        location ~ \.php$ {
        include /etc/nginx/fastcgi_params;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        }

}

configuration under /etc/nginx/sites-available/ is attached

server {
    listen 80;
    listen [::]:80;
    root /var/www/csgg;
    index i index.php index.html index.htm;
    #server_name  csgg.in;

    client_max_body_size 100M;
    autoindex off;
    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
         include snippets/fastcgi-php.conf;
         fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
         fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
         include fastcgi_params;
    }
}

Can someone shed some light on how to get PHP-FPM to start behaving normally? I am able to access .txt and .HTML files in the root folder.

Hi @csggindo,

It seems you are using Nginx as a Proxy. In your domain.conf configuration file you’ve added the following block

        location ~ \.php$ {
        include /etc/nginx/fastcgi_params;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        }

This will redirect all .php files to localhost on port 9000. If nothing is listening on that port then your server won’t be able to serve anything hence throwing that error.

I’ll recommend removing the proxy pass to see if everything would work.
