Stripe integration doesn't work

Hello, I want to purchase your plugin, but before buying, I wanted to test the Stripe integration. So, I used your demo site, here is my link: https://moral-starling-0377ca.gravitydemo.com. I went to the plugins and activated both Stripe and Mollie. The integration with Mollie works smoothly, but with Stripe, it’s impossible. When I click on “connect with Stripe”, I’m redirected to the Stripe website, I log in, choose my account, and as soon as I’m redirected back to the Stripe configuration page on the gravity form settings, nothing changes. I tried adding the webhook, entered the secret key, but nothing changes. I even tried in live mode and test mode.

please can you help me ?

we have the same problem, we use this solution from a few years and it was always ok, but from yesterday i can’t connect new account. Is it problem with stripe system?

The connection issue was caused by a temporary issue at Stripe’s end. Please try connecting again.
