    @yunse thanks for reaching out – this error has to do with Mailchimp’s Akamai API gateway blocking traffic from servers that might have some sort of bad activity on record – and is typically happening on sites that are hosted on servers that make use of a shared IP address.

    Who is your host?
    Do you have a dedicated IP address already?

    If you don’t use one currently – it’s recommended to get one for your site and there is a super simple way to have all outbound traffic go through that new IP address by using a config in your wp-config.php file. This should allow traffic to continue to submit to Mailchimp.

    define('MAILCHIMP_USE_OUTBOUND_IP', '');

    Can you give this a shot and see if it solves your issue?

    I have no dedicated IP address. But it was working fine for a year and now it is not working anymore. How can I solve that without getting a dedicated IP address. Because that costs.
