Stripe not connecting

I'm trying to build a donation form but Stripe is not connecting. It just keeps spinning and saying Connecting...

Hello,

I have checked your form and it is setup in Test mode. Please change to Live mode and then connect:

The test mode works with different test credentials. I cloned and tested your form in test mode and it is getting connected.

As mentioned, please connect in Live mode and then connect to Stripe. Finally Save the payment settings.
