Hi,We occasionally get the subject error while downloading using NSURLSession. We set 60 seconds to the NSURLSessionConfiguration.timeoutIntervalForRequest property. But, we get the error in from 12 to 20 seconds. When a response doesn't come for more than 60 seconds, we get another error with _kCFStreamErrorCodeKey=-2102.I couldn't locate definitions of _kCFStreamErrorCodeKey in headers. Can someone let me know what the error code key is and what the value 60 means?Thank you,sukeza

We're proving a free *****-access WiFi network. • Users select the WiFi hotpsot in Settings > WiFi• Captive Network Assistant tear sheet pops up• Users log-in via the Captive Network Assistant and are authenticated• Users can click "Done" button top-right of the CNA tear sheet to close it - or Users can click on the captive portal content to view web pagesWhat we'd like - and we have seen this before - is to open any web content in Safari rather than in the CNA micro-browser in the tear sheet.It used to be the case that if one provided a full URL as a link, once the CNA was connected [eg. you see the "Done" button top-right] clicking in this link would open web content up in Safari.Now this functionality seems deprectated. This is a major issue as it means once users are logged-in we cannot offer them links to other areas of the capitve portal, such as news or service updates. They're just dropped back into Settings > WiFi and would then need to manually boot Safari and visit more pages. Not a great user experience.Any ideas? Seems like there are quite a few threads on this but with no definitive answers from Apple.

When I install the thunderbolt Ethernet adapter with it connected to a switch the switch shows the gigabit connection with the LEDs but the MacBook doesn't show the connection as being active.

Does such a thing exist anywere?Thanks for any help you can provide.

I'm trying to use URLProtocol for implementing JWT authentication.The authentication flow would look like this:A request ist sent to the server. If the server returns 401 (WWW-Authenticate: Bearer realm="example.com"') the user needs to provide his credentials. With those credentials a request to the authentication server will return a valid access token. This access token is then used for the original request by setting a custom header.There are multiple issues I'm facing:didReceive challenge: URLAuthenticationChallenge, completionHandler is not called with Bearer authenticateioninside didReceive challenge: URLAuthenticationChallenge, completionHandler I don't find any way to append the header to the original requestif the user takes longer to provide his credentials than the timeout of the original request, the request would run into an timeoutIs seems that there is no way to use URLProtocol for handling token based authentication, is it?Is there any alternative suggested way to handle bearer authentication without using frameworks like Alamofire or Moya?

When building an app, is it possible or restrict or prohibit all network access for the app at the permission level? I am using React Native with hundreds of npm modules, and I want to ensure there is no data leakage from my app. It does not need internet access, so I would like to shut down all access, period.

Hi, I am working on a VPN app that use NEPacketTunnelProvider, the app has a Today Extension that allow me to control the VPN connection, start and stop the connection. I am able to load the NEVPNManager from Preferences in Today Extension, which is created in the Host app, and I am able to start the tunnel using this NEVPNManager.Everything is going well.But when I make some changes to this loaded NEVPNManager in Today Extension, for example:manager.isOnDemandEnabled = trueand try to save the manager, I got the following error:-[NEVPNManager saveToPreferenc:337 Failed to save configuration: Error Domain=NEVPNErrorDomain Code=1 "configuration type is wrong" UserInfo={NSLocalizedDescription=configuration type is wrong}I am pretty sure that the configuration is valid, at least the same code works in the Host app. And if I remove the above changes (modify properties, save to preferences), the code also works in Today Extension, which means I can start the vpn tunnel normally in Today Extension.So my question is, can I change the properties of NEVPNManager in Today Extension instead of the Host app, and save the changes to preferences, so that changes will take effect next time I start the tunnel? And how? if it's possible.Thanks!

I`m trying to make my own OpenVPN client using NetworkExtension. I'm following these instructions:https://github.com/ss-abramchuk/OpenVPNAdapterBut I cant get it to work. I create my manager succesfully, without any errors. But then when I call startTunnel() nothing happens. No error (I have my try/catch in place) and nothing in the log. I have the NetworkExtension entitlements in both my targets. This is the code in question:NETunnelProviderManager.loadAllFromPreferences { (managers, error) in guard error == nil else { NSLog("Unexpected error: \(error)."); return } / if (managers?.count != 0) { do { NSLog("Found VPN with target \(managers?[0].localizedDescription)") managers?[0].isEnabled = true; try managers?[0].connection.startVPNTunnel(); } catch { NSLog("Unexpected error: \(error)."); } } / else { NSLog("Not found, creating new"); let manager = NETunnelProviderManager(); / guard let configurationFileURL = Bundle.main.url(forResource: "config", withExtension: "ovpn"), let configurationFileContent = try? Data(contentsOf: configurationFileURL) else { fatalError() } let tunnelProtocol = NETunnelProviderProtocol() tunnelProtocol.serverAddress = "" tunnelProtocol.providerBundleIdentifier = "com.vpn.***.TunnelManager"; tunnelProtocol.providerConfiguration = ["ovpn": configurationFileContent] manager.protocolConfiguration = tunnelProtocol manager.localizedDescription = "My VPN" manager.isEnabled = true / manager.saveToPreferences(completionHandler: { (error) in if let error = error { print(error); } manager.loadFromPreferences(completionHandler: {(error) in do { try manager.connection.startVPNTunnel(); } catch { NSLog("Unexpected error: \(error)."); } }) }); }I changed the blunde identifier for privacy reasons.I hope somebody can help me with my problem, if you need the contents of another file, or any other information, please ask.Thanks in advance.
