I recently installed Gravity Forms, added the MailChimp add-on, but when I tried to add any feeds, this came up: http://i.imgur.com/xoGfrdF.jpg
Could not connect (ERR 110: Connection timed out)
What could cause this?
There is some sort of communication problem between your web server and the Mailchimp server. If the issue continues, you should look for error logs on the server to see what sort of communication error there might be which could be causing this.
If you're not able to find any errors logged in that way, I can send you a logging add-on which may help pinpoint the issue. If you're like the logging add-on, please send an email to firstname.lastname@example.org and reference this topic.
I've installed the logger, but the message didn't became clearer. Could you guess why our server can't connect? Is there a setting or configuration that could hinder the connection?
Or... is it simply that the API key is somehow wrong? I've created multiple keys and got the same response.
2013-03-25 14:37:33 - DEBUG --> Validating login for API Info for key <KEY> 2013-03-25 14:38:03 - ERROR --> Login valid: false. Error -99 - Could not connect (ERR 110: Connection timed out)
There is no setting in the plugin which can affect this. It does not look like there was an answer indicating that the API key was wrong. I still believe there is something on your server preventing communication with the Mailchimp server.
I would check with your host to see if there is anything logged. The Mailchimp API requires the PHP function fsockopen. Can you see if the host has that enabled in your installation?
You can do a quick test to see if the function is available. Insert this code into a file called "fso.php" and install it on your server at http://example.com/fso.php (use your URL instead of example.com). Pull that up in a browser and see if fsockopen is available for your use or not.
[php] <?php if(function_exists('fsockopen')) echo "fsockopen function is enabled"; else echo "fsockopen is not enabled"; ?>
The function is enabled. I'll check with the host, and post if I get some results. Thanks!
