Request failed with http status code 503

Hi, I am trying to write an app for macOS which will allow or drop a potential upload request, e.g. PUT or PATCH http request. For example, I would like to block uploading of a file to Google drive. I was looking into the 'SimpleFireWall' app sample provided within (https://developer.apple.com/videos/play/wwdc2019/714) but AFAIU this cannot be done due to limitations of NEFilterDataProvider and its flow (NEFilterFlow) objects, i.e. one limitation is that this would only be supported on Safari (WebKit based browsers) and secondly there is no option to peek and analyze which http request is represented by the flow in case of a TLS connection (HTTPS) as data is obviously encrypted. What would be the recommended way of achieving this? Thanks, Doron.

Hello, I'm working on non-consumable IAP's and when I try to validate a receipt, I always get this status code 21002, which means my receipt-data property was malformed or missing. But I've been doing exactly how I saw on apple's documentation. What am I missing? guard let receiptFileURL = Bundle.main.appStoreReceiptURL, FileManager.default.fileExists(atPath: receiptFileURL.path) else { return } let receiptData = try? Data(contentsOf: receiptFileURL, options: .alwaysMapped) guard receiptData != nil else { UserDefaults.standard.set(false, forKey: isSubscribed) return } var recieptString = receiptData?.base64EncodedString() ?? let jsonDict : [String : Any] = [receipt-data : recieptString, password : Constants.ConstantValues.autoRenewableReceitPassword.rawValue, exclude-old-transactions : false] let httpBody = try? JSONSerialization.data(withJSONObject: jsonDict, options: []) let storeURL = URL(string: Constants.ConstantValues.verifyReceiptSandboxURL.rawValue)! var storeRequest = URLRequest(ur

FB9895426 (Apple Device MDM enrolment fails if client certificate is requested during SSL Handshake) Device enrolment fails in an MDM Server configured with client certificate authentication. Upon investigating the issue, we noticed that the device drops the SSL handshake if a client certificate is requested during the handshake. Wireshark Screenshot: From the console logs, we noticed the below error: cannot accept the authentication method NSURLAuthenticationMethodClientCertificate The TLS protocol states that If no suitable certificate is available, the client SHOULD send a certificate message containing no certificates.. Thus, we expect the MDM client to respond with a no certificate response during the SSL handshake. Someone has already raised the same question but there's no reply yet: https://developer.apple.com/forums/thread/680328 https://developer.apple.com/forums/thread/676579 Any help would be appreciated. Thanks in advance.

We would like to make a distinction as to which request was served via HTTP/2 or HTTP/1.1I looked HTTPURLResponse api and other api's in CFNetwork to see if we can determine this. I have however not been succesfull in finding if the specific API is served as http/1.1 or http/2Is there a API call I'm missing that would give this information?Thank you,Sohil
