While doing payment with Paypal Sandbox suddenly it gives below error
I'm sorry – but we were not able to process your payment. Please try
another payment method or contact us so we can assist you.
In the log error it says
main.CRITICAL: PayPal NVP gateway errors: Instruct the customer to
retry the transaction using an alternative payment method from the
customers PayPal wallet. The transaction did not complete with the
customers selected payment method (#10417: Transaction cannot
complete). Correlation ID: 620934b68a59c. Version: 72.0.
I tried to reenter credentials but still it gives same error.

I resolved this issue by just changing "Transfer cart line item" to "Yes" in admin panel from path Store > configuration > sales > payment methods > PayPal express checkout > Basic setting PayPal express checkout > advance settings.
