 * We are having issues with clients no being able to use plugins that make calls
   to the mailchimp API. We have opened ports 80 & 443 but we have been unable to
   determine a cause of the issue. Whenever I enter an API for an account I get 
   the following error…
 * Uh-oh, we were unable to verify your API Key. Please check them and try again!
   
   The server said:Could not connect (ERR : )
 * I have no ERR code so I have no idea what is causing the issue, any advice would
   be appreciated. I am testing on a brand new install of WP.

 * Hey Adam,
 * Thanks for posting. That definitely sounds a bit odd, especially with the error
   message missing. Can you confirm if your plugin is up-to-date, and also whether
   there are any other active plugins on your installation? If so, can you try disabling
   the other plugins to see if this resolves the issue?
 * If it is in fact an issue with the local install, it’s tough for to troubleshoot
   the specifics of the environment from our end, but I’d be happy to help in trying
   to isolate the issue. Can you send us an email at mailchimptk[at]gmail.com with
   just your MailChimp account’s username? No passwords please. I can then try using
   the API key on your account to try and connect through my local setup, and confirm
   that the MailChimp side of things is working just fine. When you do send the 
   email, please make a post here notifying me that you have. That way I’ll be notified
   and can get back to ya sooner. Thanks!
