Why is my payment submission failing on my ecommerce platform?

Hi! I just set up my payment account on Shopify and I trying to submit info requested by Shopify in order to continue collecting payment. But the problem is that after completed the form and hitting “submit” THE BUTTON TURNS INTO SPINNING WHEEL, THEN IT REVERTS BACK TO “submit” without having submitted the info. I have clear the browsers data and tried again, I also tried in different devices but it NOT WORKED. What do I need to do, please help!
