I checked your billing method and it looks like your issuing bank declined this transaction. Kindly check this with your issuing bank for more information on why this transaction was declined.
In the meantime, you can try adding a different billing method to be able to purchase Connects for your Upwork account.
My friend, I am just a freelancer.
Debit Card that you are using in “Billing&payments” may not be compatible with international payment. First make sure that the Debit Card you added to the “Billing&payments” is suitable for international payments, as some debit cards are not compatible with international payments. Even then, if you face the same problem, please contact the payment issuing bank and inquire why the payment is being declined.
I hope, the issue will be resolved.
Please sort out the exact cause of the problem before proceeding further any more.
