Form not working after change in server to mitigate DDOS Attack

It appears the changes made to mitigate the DDOS attack have left my most profitable form dysfunctional. I'm hoping tech support can fix it.

Hi Duncan,

Thanks for reaching out to Jotform support and we're very sorry to hear about your experience. If you can share the link to your form, we can check it out and see what's going on. Also, explaining more about the issue such as how the change affected your form, or what's not working as expected on it will help us get a better understanding of what's happening.

After we hear back from you, we’ll have a better idea of what’s going on and how to help.
