Can you help me with this issue: 'Sorry, we could not accept your submission at this time. Please try again.'?

We have campaigns running, and all our landing pages that we checked are unable to collect any submisions. Everyone that is trying to complete and submit a form from a landing page receive at the end the mesage: ‘Sorry, we could not accept your submission at this time. Please try again.’. Can everyone guide us in the rigth direction?

For example, from an older campaign: https://xf463-0186b8.pages.infusionsoft.net

I’ve just tested your page with one of my test accounts and it worked fine.

This type of issue i would tend to immediately engage with chat support or phone support
