You could contact MailChimp about this as they are able to check this for you. * Are you running the `curl ....` command check from the same computer your website is hosted on or from your own computer? * Thread Starter [Kodran](https://wordpress.org/support/users/kodran/) * (@kodran) * [10 years, 6 months ago](https://wordpress.org/support/topic/getting-403-error/#post-6795177) * Update 2: * Just checked the plugin and now it says “Connected”. * I don’t know what happened but now it seems to be working. * Thank you for your support and good luck with further development. I think this is a really solid plugin.
