500 Error

Hi there,
for the past 12hours, I have been having this error.
Mailchimp says: API Request Error – on 1544 on \includes\api\class-mailchimp-api.php

This line refers to 500 HTTP error.
I already created new API keys. and changed them in the plugin. No success.

From my readings seems to be an issue with MailChimp Server. No new plugins, no changes were done to the website.

The account on MailChimp is not suspended or under review, so I’m almost sure that the error 503 i get from another plugin (Mailchimp for WordPress) isn’t applicable for this case (I hope it’s not 503 “Service Unavailable” – your website is blacklisted by the Akamai firewall ).

Please advice on the best way to proceed.

Thank You
Kind Regards
