I`m sorry about the inconvenience this had caused you. Your contract is suspended due to a problem on your client's end. Our team is working with your client to resolve this as soon as possible, once it's resolved the hold on your contract will be lifted as well. Thank you.

Upwork will not tell you that, it is between Upwork and your client.
Whatever the issue is, your client needs to sort it out with Upwork. Do not work for that client until it is resolved officially.
