Errore HTTP:Errore Curl 7:Impossibile connettersi alla porta 80 di WordPress.org?

Ho appena installato un server Ubuntu 16.04 con LEMP e wordpress.
Ma sembra che mi sia perso un passaggio nel processo, poiché ho il seguente errore sui siti Web.

http error: curl error 7: failed to connect to wordpress.org port 80.

I siti funzionano bene oltre al fatto che è configurato in una macchina virtuale mentre sto sviluppando un sito Web, prima sulla mia macchina locale per testare tutto in locale.

Ecco il mio file di configurazione:

server {
        listen 80;
        server_name 192.168.1.3; #ipaddress;
        root /usr/share/nginx/mrupgrade.be/;
        index index.php index.html index.htm;

        error_page 404 /404.html;
        error_page 500 502 503 504 /50x.html;

        location = /50x.html    {
                root /usr/share/nginx/html;
        }
        location / {
                try_files $uri $uri/ /index.php;
        }

        error_page 404 /404.html;
        error_page 500 502 503 504 /50x.html;

        location ~ \.php$ {
                try_files $uri = 404;
                fastcgi_pass unix:/run/php/php7.0-fpm.sock;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;
                root /usr/share/nginx/mrupgrade.be/;
                }
        }

Nota che ho configurato il firewall con queste regole:

Quindi nell'immagine va tutto bene aspettati alcune cose forse manca una lib o non so di aver installato fpm fast cgi.

Il wordpress non riesce a connettersi al web con la richiesta http.

Non so davvero cosa potrebbe essere qualsiasi indizio sarebbe il benvenuto.

Grazie in anticipo per il tuo aiuto.

Risposta accettata:

Il tuo server si chiama wordpress.org?

Secondo il tuo file di configurazione è:

server_name 192.168.1.3; #ipaddress;

Se si desidera utilizzare un nome server in locale, è necessario inserire l'indirizzo IP e il nome in /etc/hosts e, se deve essere accessibile esternamente, è necessario disporre di un nome host e di una voce dns dal proprio ISP. E devi impostare il port forwarding appropriato nel tuo router.
