How can I get my mail chimp API to connect to jot form?

I have found where it is to enter the API info but when I enter it it just takes ages to load, like over an hour! I know it is not my internet connection because I have managed to load other web pages but what can it be?! 

I checked your form and you've managed to integrate the form with MailChimp. I presume this is resolved.

I also could not reproduce the problem.
