Why is my payment gateway not working on my online store?

Need help I opened my store before 3months. I activate 3 payment setup. But its not working. When I try to test order Its showing error. What do I do

Hi @Famigliatjd

Thank you for the screenshot showing the error message at the checkout. Who is the payment gateway you are using on your store that isn’t working?

You will want to ensure your account with them is properly setup and in good standing. I would also try disconnecting and reconnecting the payment gateway to ensure your account is properly signed in with them. If you continue to have issues you will need to contact the payment gateway directly for further support.

I just now disconnect all the payment setup and try to reconnect them
