Upwork rejecting my transaction to paypal.

[#1]

For some reason Upwork is not sending my funds in my paypal account and Im getting this message in my email:
We attempted to process your recent payment request but unfortunately it failed.
The reason for returned funds: Unable to apply funds.
As a result, the funds have been returned to your Upwork account and we need you to update your payment method for future payments.

I need help asap.
