Sorry to hear that. My client's payment went through. I heard from him that he had an issue with his payment method that he sorted out with UpWork on Friday.
It is important to know that you shouldn't do any work for the client until UpWork reactivates your contract. If you were under the hourly contract and tracked your time via the tracker, then you should get paid by UpWork no matter whether your client pays them or not. This is applicable only if you have notes in your work diary that describe what you did and if your activity level was high enough. Otherwise, it is not applicable. It is also impossible to get any payment from UpWork if your contract is fixed-priced or if you tracked your hours manually. But I hope your client will sort out the payment issue on their end.
Good luck.
