Customers are having issues processing the orders at payment screen

I had a customer try to place a purchase, but it would not go through, so I tried a test, and it would not go through. I placed the order via Paypal, and it went through. Not sure what to do at this point. All worked when we launched the site, and now it is not working. When it stopped working not, sure.

poolrestoration.com is the site name.

@keithkk here is the information I already sent you, but I’ll share it here also for anyone else who might be having the same issue.

If you are receiving a 10069 error code from PayPal, preventing the order from being processed, we recommend contacting PayPal customer support for further investigation. This is the best course of action to resolve this issue. We hope this information is helpful for anyone else encountering this issue.
