Mailchimp Integration Error 404

I’m having some trouble integrating newsletter with my website email. The website is integrated with Mailchimp, and every setting seems to be correct, but still, the newsletter is not taking email addresses to subscribe to the list. There’s an error when I go to MC$WP>Other. I’m attaching the screenshot of the same. I’m not well versed in codes and API keys, so please let me know what’s the issue and how I can fix it.
