Mailchimp API is invalid Error 401 Flow Logic

I did all the steps correctly, but I am still getting this error message:

Do I have to do something on my godaddy site domain registrar…

Here is my site Read-Only: LINK
(how to share your site Read-Only link)

I have the same problem, have you resolved it?

Can someone please answer this question?

I have exactly the same problem, everything seems fine, followed entire tutorial from Add subscribers to Mailchimp with Webflow Logic - Webflow University Documentation
And what OP shown in his print screen is what I have also

Is this a webflow or mailchimp bug?
