blocked ports?

[Cleon]

Hi all,

I've written a php script that trys to connect to my personal network camera and return the current frame image (jpg).

When my home router gets a request on port 81 it redirects it to my camera.

This set up works fine if I surve up the php at home. But when I serve it up from hostgators server I get a "can't connect to host" error from the php script.

I was wondering if it was maybe because HG was blocking access to port 81?

The php looks something like this (if someone is interested):

PHP Code:

<?php

    $ch = curl_init();
    
    $url = "http://myhomerouteraddress:81/theimageiwant.jpg";

    // set URL and other appropriate options
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
    
    // grab URL and pass it to the browser
    $content = curl_exec($ch);
    if ($content === false){
        echo '<pre>';
        echo curl_error($ch)."\n";
        echo '</pre>';
    }
    // close cURL resource, and free up system resources
    curl_close($ch);
    
    echo $content;    

?>

Anybody got clues?

Thanks in advance,
Cleon

I assume you are using a FireWall? You probably need to enable port 81 in.

Thanks for the suggestion but I don't think thats the problem as I can access that port 81 url from another computer at my friends house for example

Yes.
All ports are blocked by default, and only those are open that need to be open.
You can contact HG support and ask if they can open that port for you.
Or if it's possible for you to use some other port they could suggest an already open port.

Thanks for confirming, I'll get in contact with support
