Why are my customers unable to checkout due to payment issues?

why isn’t it letting my customers checkout? it says “there is an issue processing your payment. Try again or use a different payment method.”

It is happening to all my customers.

Hi, @gatewaykartplex .

Thank you for reaching out! I am sorry you are experiencing issues with your payment gateway.

I will need to gather some information before diving into this with you. What payment gateway are you using? Can you provide your URL so I can test this on my end?

Please let me know if you have any further questions!

Talk soon,
