PayPal Smart Payment Buttons - Can't process cards

Getting a very generic message when a card will not process. Using know, good cards to test.

the message says:
We're sorry, but weren't able to add this card. Try again later or add a different card

Any ideas of the casue. Everything work great in our test environment.

Which nopCommerce version?
Have you configured paypal properly?
Any error message on back admin Log list?

4.3
I believe it is configured correctly. It has processed cards correctly before, but we noticed that sometimes it did not.
I did not find any error in the logs.

In chrome console, I see some errors. I cant' attach the picture here. These are some of the lines typed out.

I think we are going to try another plugin first.

Any errors in the log ?
