Thank you for contacting us! I think the issue is had something to do with your form URL. Instead of https://secure to make form secured, your form is only using https://form and that causing the issue.
Here is your Form URL which is working fine now.
To avoid this from happening again, I would suggest you to always enable the secure form option of your form. Please take a look at this article for more detailed information.
If you need further assistance, please feel free to contact us again at anytime.
Have a nice day!
