Unable to run OpenTok's WebRTC demo - php

Question

Recently I tried to use OpenTok's WebRTC demo for a web application requiring peer-to-peer video/audio communication.
I went through the tutorials on http://www.tokbox.com/opentok/webrtc/docs/js/tutorials/ and http://www.tokbox.com/opentok/docs/server/server_side_libraries.html and I got something working using JavaScript (client-side) and PHP's library (server-side) for token/session generation.
I managed to code a basic peer-to-peer chat room locally. However, as soon as I upload it to a web server it blows up returning the following error:
Fatal error: Uncaught exception 'RequestException' with message 'Request error: Failed
to connect to 70.42.47.98: Permission denied' in /home/www/dummy_url.com/php-
sdk/SDK/Opentok-PHP-SDK/OpenTokSDK.php:192 Stack trace: #0 /home/www/dummy_url.com/php-
sdk/SDK/Opentok-PHP-SDK/OpenTokSDK.php(107): OpenTokSDK->_do_request('/session/create',
Array) #1 /home/www/dummy_url.com/php-sdk/SDK/Opentok-PHP-SDK/OpenTokSDK.php(221):
OpenTokSDK->createSession('74.96.245.119', Array) #2 /home/www/dummy_url.com/php-
sdk/index.php(16): OpenTokSDK->create_session('74.96.245.119', Array) #3 {main} thrown
in /home/www/dummy_url.com/php-sdk/SDK/Opentok-PHP-SDK/OpenTokSDK.php on line 192
I took a look at line 192:
//die(function_exists('curl_version')); // debugging
$res = curl_exec($ch);
if(curl_errno($ch)) {
throw new RequestException('Request error: ' . curl_error($ch)); // <=== LINE 192
}
curl_close($ch);
and verified the server had curl enabled. It does.
Then I tried to run the demo test and it fails at:
Assertion Failed: File '/home/www/skillfullearning.net/test/test/TestOpenTokSDK.php'
Line '102'
Code ''
What's in Line '102'? This:
...
$token = $a->generateToken("mysession", RoleConstants::MODERATOR, gmmktime() + 100000);
assert('$token');
$token = $a->generateToken("mysession", RoleConstants::MODERATOR, gmmktime());
assert('$token');
try {
$token = $a->generateToken("mysession", RoleConstants::MODERATOR, gmmktime() +
1000000);
assert(false);
} catch (Exception $e) {
assert('$e'); // <================ LINE 102
}
...
I really don't know where to go from here. I would really appreciate some help with this matter.

The error is caused by outdated tests. Here is an outstanding issue, hopefully it will be resolved soon. if you simply remove the test files, you would not have that problem anymore.
