The 3rd line is logged when connection:didReceiveResponse: is called, we can see that the server is returning a 200 HTTP status code. URLRequest_Users_Profile - Request did fail with Error (Code 200) : La connexion réseau a été perdue. URLRequest_Users_Profile - URLRequest did receive HTTP response : 200 _tcp_connection_write_eof_block_invoke Write close callback received error: Invalid argument nw_endpoint_handler_add_write_request cannot accept write requests I just reproduced the issue in my project using NSURLRequest / NSURLConnection, where the delegate method connection:didFailWithError: was called.

However, sometimes, requests behave as if they have failed. I can confirm that most of the time, NSURLConnection recovers from these errors and everything goes as it should. Thank you for your quick reply (and sorry for my late answer). Obviously, none of it solved this yet in my case. I tried doing some research but have found very few threads talking about this, with people saying they resolved it with the weirdest fixes, like fixing the App capabilities in Project Settings or adding some missing Privacy Reasons in ist. Have you guys encountered a similar issue on iOS 10 ? I tried creating a test project that would send the requests to the same server by using the newer NSURLSession APIs, but the issue is still happening, so it would seem like it's not a bug related to NSURLSession. I tested it on 3 different Wifi networks at home and at work, and I can confirm that the issue happens on all 3 networks.Īlso, the issue happens on my app built with the iOS 9 SDK, and recompiling it with the iOS 10 SDK doesn't solve the issue. I never encountered the issue when using a cellular connection yet. It only happens on my devices running iOS 10 (10.2 beta included), the same app running under iOS 9.3 runs fine, and the weirdest thing is that the bugs only seem to occur when the device is connected on a Wifi network. _tcp_connection_write_eof_block_invoke Write close callback received error: Socket is not connected

nw_connection_write_close 18 Connection is not ready, sending error callback nw_connection_read 18 Connection is not ready, sending error callback These failures produce some system logs though : I got an app still using the old (deprecated) NSURLRequest / NSURLConnection APIs for networking, and my requests randomly fail for a reason that seems unclear to me. This is a bit long, but personally I prefer to use the standard C defines in my code.I keep stumbling on a weird issue on my devices running iOS 10.
