CURL Call With Port In Url / Location Not Working - Couldn't Connect To Host

I am trying to make a cURL call to a url that looks like this: [URL].... When I execute the following code, I get curl error 7 couldn't connect to host.


If I set the url to [URL], I am able to connect to the host, just not to what I need to get. I have also tried setting <code>CURLOPT_PORT => 9000</code> with the same result (error 7). One other note, I am able to use cURL with the url on some machines but not others. My Windows machine works fine, but the linux server I'm on is the one having issues. Another linux server seems to work fine as well.

Google Adword Client Library Couldn't Connect To Host

Im working on connecting my website to connect to Google Adwords to create ads and campains depending up on the products in my site. I tried connecting by sending direct curl request and parse the received SOAP response. But that is too becoming complex for each request. So i tried using the PHP client library provided in Google Code. But none of the example is working correctly. I changed the user account details in auth.ini file but still on excecuting the example files it says

Failed to get authToken. Reason: couldn't connect to host'. I tried running the scripts in different servers but still getting the same error.Following is the code to fetch all ads from Google adwords and this is a example file from Client library

Apache - Curl Cannot Connect To Host On Own Server?

I have a PHP script that uses cURL to access a file also located on my server (installed email marketing program). I wrote a quick script to test my cURL installation and it fails when pointed at a file on my own server. The script is:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$contents = curl_exec($ch);
if($contents) {
echo $contents;
} else {


If I change the URL to [URL] or any other site, it works just fine. Also, when I try to open the specific page via cURL on another server, it works like it should. The assumptions I'm making from these tests is that the PHP cURL is installed and (kinda) working and that the problem is not in the page that is trying to be opened.

I thought it might be a port issue, so I tried specifying the port with the same result (not connecting to host). I tried both curl_setopt and [URL] to specify a port I know to be open.

This leads me to believe that the issue is something in my apache installation, but I'm not an apache expert and I've been banging my head against Google all day to no avail. what could cause such a specific cURL failure?

Error Log Stating That It Could Not Connect To Smtp Host On Port 25

I have some code which sends an email to a recipient, but it is not working. I have checked the smtp host and port in the PHP.ini file and both are correct, I have also contacted my provider and know the smtp host and port are also the correct ones.

I am getting an error on apache's error log stating that it could not connect to smtp host on port 25. Notice that I am using the smtp host name, I can also ping it so I know I can get to it.

At one point, the emailing function worked, but it has now stopped working; not sure what the problem might be. I have actually created a mailtest.php with some very basic code to no avail.

Fatal Error: SOAP-ERROR: Parsing WSDL: Couldn't Load From

In PHP, if you try to instantiate a new SoapClient, and the WSDL is not accessible (server down or whatever), a PHP fatal error is thrown:

Fatal error: SOAP-ERROR: Parsing WSDL: Couldn't load from''
: failed to load external entity "" Fatal errors in PHP, as far as I know, are not recoverable. Is there any way to fallback from this? Can this fatal error somehow be avoided?

Edit: I should say that I am running on PHP 5.2, if it makes any difference.

Receive "Internal Server Error" When Trying To Connect To FTP With Curl?

I keep receiving an "Internal Server Error" trying to connect to an external FTP connection with Curl. I can access the FTP fine normally, but not through Curl.I'm using CodeIgniter as a wrapper, but I really don't think that will cause such an issue. I've tried increasing my memory/timeout, but I still can't get in. The 500 internal server error is actually on my page; I can't figure out if Curl is returning anything, but I do know that I just get a normal error through Curl (not an internal server error) if I disable the 'username' or trying to add a 'password' (there is no password for this FTP Login).Here are my main scripts:
