Invalid Resource error 400

Form is working fine but will not import contacts into mailchimp

Here is my error report

I am not a programmer – I just get by
I used stand tags for contact form 7

<label> First name
    [text* your-name] </label>

<label> Last name
    [text last-name] </label>

<label> Email
    [email* your-email] </label>

<label> Phone
    [tel* your-phone] </label>

[submit class:pushbutton-wide "Get Started"]

Can someone assist?

Thanks
