WPForms, Stripe, Wordpress Integration

My Wordpress website uses a WPForms and Stripe integration to process customer payments. For some reason, when forms are submitted, there is an error message showing that the payment can not be processed, and therefore the form isn't processed, and no payment is processed through Stripe. Upon checking Stripe's logs, there is an attempted connection for payment to be made, but something is preventing the payment from being successfully processed. I have not changed/updated my website, so Im not sure why the connection is broken. I tried to disconnect, and reconnect Stripe to the website via WPForms settings but it did not work. I also disabled my server's firewall, and it still didnt work. I need someone skilled with not only Wordpress but also WPForms plugin to diagnose what could have happened, and fix it within 24 hours.
