Problem Installing Powerstore cURL Error

Hi,
when running the install procedure for Powerstore 4.5.3 on my server I get this error message:

"PowerStore 4 Installation Wizard
STEP 1 OF 7
This Server Diagnostic Check analyzes your server to ensure the necessary permissions and settings are enabled for PowerStore to work properly.

When running this script (http://www.webassist.com/forums/showpost.php?p=87177&postcount=7) it reads: "Curl error: couldn't connect to host"

Any suggestions?

Your host is not allowing the cURL connection to be made to the webAssist servers, you will need to contact the host and have them lift the restriction for cURL connecting to the webAssist server.

Great, now it works! Thanks for the support!

Jason do you know how to lift this restriction for a local testing server (WAMP) MySQL 5.6.17, PHP 5.5.12, APACHE 2.4.9?

Can you connect to other servers with cURL? Like this:

$ch = curl_init("http://google.com");    // initialize curl handle

    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

    $data = curl_exec($ch);

    print($data);

I'm not a server configuration expert, but I've done a few google searches on this error. Another forum suggested:

enter - IP www.webassist.com and enter it in etc/hosts file

(I'm not sure exactly what that means, but it may be a solution)
