Possibly Unblock IP address for updates.drupal.org

All IP blocks have been cleared.

I still can't access the updates, host isn't blocking anything either. This has never happen before.

Verify that calls to fsopen() are allowed in the PHP installation running on your site. It seems that the function is disabled for security issues from some host providers.

I did verify and it's allowed but still unable to access

I apologize; I reported the wrong function name, which is fsockopen().

fsockopen() is also included so there must be another reason why. I can access them on localhost just not on the server.

Can you write a small php script that tries to access say google.com using fsockopen?

No unfortunately I'm php challenged, don't know any of that.

Try this. Name it fsockopen.php" or something else, copy it to where index.php lives and access it through your browser.

<?php
$fp = fsockopen("www.google.com", 80, $errno, $errstr, 30);
if (!$fp) {
    echo "error $errstr ($errno)<br />\n";
}
else {
    echo "google contacted";
}

tried that and it shows google contacted

what happens if you replace www.google.com by first www.drupal.org and then updates.drupal.org?

I get this message with drupal.org

Warning: fsockopen() [function.fsockopen]: unable to connect to www.drupal.org:80 (Network is unreachable) in /utest.php on line 2
error Network is unreachable (101)

and with updates.drupal.org

unable to connect to updates.drupal.org:80 (Network is unreachable) in /utest.php on line 2
error Network is unreachable (101)

can you try "drupal.org" instead of "www.drupal.org" and "updates.drupal.org" also without www?

The host fixed it, I send them the messages and they got it working again.
