Stripe Payment Failed

I have followed all the videos and tutorial on how to setup Surecart and Stripe. But until now all the payment still failed to go thru. The connection to Stripe and Surecart has been connected successfully on the first time setup but still the payment still failed.

More frustrating is it just show a one word error in red color – “error” . This is not helping at all to troubleshoot – https://d.pr/i/igieis

I am pulling my hair now, I don’t know what to do.
