Forbidden 403 – Reference number

Hello!

we have been using your plugin in our website slator.com for a couple of months without any problem, but it suddenly disconnected from Mailchimp. We now receive the 403 Forbidden error response: screenshot

I read a related ticket also called “Forbidden 403” but we couldn’t find a solution in it. I run the curl command and we get a HTTP/1.1 200 OK response:


-bash-4.2$ curl -v https://us10.api.mailchimp.com/3.0/?apikey=xxxxxxxxxxxxxxxxx-us10

We also contacted Mailchimp’s support and they said:

“When the cURL command was run, we were seeing a response of 200 OK, which shows that our system is able to give a positive response when connecting to that IP address.
With that said, we definitely want to investigate why the 403 error is appearing. In order to do so, we’re going to need the reference number associated with the 403 forbidden error. In order to get this reference number, you might want to reach out to the developer of the plugin to see if they can provide that information.”

Could you provide us the “reference number”? Any idea of what the problem could be? Our host is MediaTemple.

Many thanks for your help.

Kind regards,

Gustavo
