No response from API for several days (everything was working fine before)

API
1

Hello, I have been trying to use the API for several days but I have no response. I checked my settings (subscription, key, etc.) but no response to my Query.

My code in SwiftUI :

openAI.sendCompletion(with: query, maxTokens: 500) { result in
            DispatchQueue.main.async {
                switch result {
                case .success(let success):
                    if let chatGPTResponse = success.choices?.first?.text {
                        self.answers.append(chatGPTResponse)
                        print("Response received: \(chatGPTResponse)")
                    } else {
                        print("No text in response")
                    }
                case .failure(let failure):
                    print("Error: \(failure.localizedDescription)")
                }
            }
        }
