            global $woocommerce;

            $boundary = uniqid();
            $delimiter = '-------------' . $boundary;

            $url = $this->server_url;
            $fields = $this->createBody($order_id);
            $post_data = $this->build_data_files($boundary, $fields);

            // create body and header
            $header = array(
              "Content-Type: multipart/form-data; boundary=" . $delimiter,
              "Content-Length: " . strlen($post_data),

    Your host might firewall off outbound connections by default, or you may need to configure your VM or VPC firewall or similar yourself depending on what your host has. Can you connect to that URL from command-line curl on the machine? – Rup Sep 2 at 9:30
  • hi @Rup $ curl --form "loginname=sang4" --form "charge_type=6" --form "site_id=258" --form "email=your@emailaddresshere.com" --form "firstname=sang4" --form "lastname=sang4" --form "cardnumber=4321432143214321" --form "cardmonth=03" --form "cardyear=2020" --form "cvv=999" --form "currency=JPY" --form "amount[0]=1980" --form "customer_id[0]=1" --form "contents_id[0]=1" --form "contents_name[0]=1" --form "token=2c4b4545a9b80dbac64f490f48cceca4" -X POST api2.something.com:8081/payment2.php – chris lim Sep 3 at 2:32
  • and the output is {"result":{"id":"","transaction":{"amount":"","transaction_id":""},"time":"2019-09-02 19:24:30.400907","status":"Failure","reason":"Input data error<b>\"\"<\/b>"}} – chris lim Sep 3 at 2:37
  • Does your stand-alone PHP script work when run from the server too? If not, I'd guess it's still networking configuration and there's an outbound HTTP proxy that you'll need to use and your shell user has the settings but not your service user. If it does, then it's either WordPress or again the service user: do you have a security plugin that might intercept PHP curl and filter outbound traffic? Are you running with selinux enabled, which might also prevent unexpected outbound connections from the web server process? – Rup Sep 3 at 8:58
