There are various ways to fix this:
Ask your webhost for a new IP address.
Migrate to a new webhost if your hosting company is unwilling to fulfill your request.
Configure your server to connect to the MailChimp API server using a proxy.
NEW IP Address – they already change this to have a new IP and is still blocked.
Migrate to a new webhost – not happening…
Configure your server to connect to the MailChimp API server using a proxy – How can i do this!? It’s a server side change or i can do it myself?
You may need to do some testing yourself – How can i perform this tests?
Thank you for your reply
