After having this module installed and configured correctly for a while, on page load where the subscription form is embed, i start receiving this drupal message 'The subscription service is currently unavailable. Please try again later'.
Message keeps coming after switching to another account, so not related to a specific list inside the mailchimp account.

Clearing the cache does seems to avoid the message from showing up again.

Is their some static variable expiring which might cause this error ?

RAWDESK created an issue. See original summary.

UPDATE:
Looks like the error is linked to cron.
Whenever cron has run (automatically), the service is unavailable error is somehow triggered..
Clearing the cache subsequently (manual) removes the symptom

I ran into a similar error. Which in the end was caused by an SSL issue. See http://stackoverflow.com/questions/22973701/ssl-errors-using-mailchimps-api

I ran into this error whenever a certain subscription form was loading. It turns out that my client had removed the subscription list associated with that form and it continued to trigger this error. My guess is because it didn't find the form in the listing of available lists it was casing the count to be zero, in turn triggering this wrong error.

Some systems does not trust Mailchimp's weak certificate. This module should take care of it.

Bobík, the same issue occurs in D8. How can I fix it?

@kwaksalver You can install MC certificate to system, see previous comments.

An incorrect api key can also be the source of this message.

I think it happens as a protection, when you send many times a request to mailChimp, is it possible?. In my case it was working this morning, I was testing, and after that I saw the messages.

I'm closing this as outdated - if there is an issue with Mailchimp's certificate or your server's SSL configuration, the Mailchimp module is not responsible. If there's something specific we can change in Mailchimp to fix this please re-open the issue with notes or a patch. Thanks!
