Why am I getting a payment processing error on my website?

[Strnad]

Hello community.
Can someone give me some advice, now I'm running my website and when I want to make an order and pay with any option (Apple pay, Mastercard, Visa, Google Pay), after clicking the Confirm button it says: ''There was a problem processing the payment. Please try again or use another payment method''?

Please solve this problem as soon as possible, it is very urgent.

my web: streetsense.cz

Hey @Strnad.

Thanks for reaching out. 
 
Just to gather some additional context, would you happen to know what specific error message your customers are receiving when they attempt to complete the checkout? I am just trying to get a better understanding of what may be occurring so I can assist you accordingly. 
 
You can check your abandoned checkouts by navigating to Orders > Abandoned checkouts. You can View payment events from an abandoned checkout by selecting an order and viewing the timeline to see if they received any specific error messages. 
 
Looking forward to your response.
