Braintree error in form

My form: https://form.jotform.com/72836174318966

At first I'm receiving a Braintree error (HTML 400) and now after I submit the form, it warns me that the page I redirect to after submission is not secure (https). 

This is the first time I've seen these problems and I've been using this same form for two years.

I have been testing your form, but I'm unable to submit it since I'm using testing payment information, the form is currently on live mode; however, I have cloned it and integrated it on my end with Braintree, testing the sandbox mode it seems to work. 

Please find my form here: 

https://form.jotform.com/73044577419967 

And use the following information to submit it: 

- Credit Card Number: 4242424242424242

- CVC : 123

- Valid Expiration Date

  *Later than the current date

I would recommend you to make sure that you're using the correct credentials, if the form still does not work, please try setting up the default thank you page, although it's redirecting to the custom one you have set up on the thank you wizard. 

If the problem persists, please let us know. 

Ok I think I have the braintree problem figured out and it's redirecting correctly again, however

Glad to know your form works now.
