Error -1005 "The network connection was lost."

Hello,

I have a problem using HTTP PUT with iOS 10 beta.

I use the code to make a PUT request. While it works fine with iOS 9.3.4 it doesn’t work in iOS 10 beta 6

   NSString *str = @"<myData>Some xml Data</myData>";
    NSData *xmlData = [str dataUsingEncoding:NSUTF8StringEncoding];


    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
    [request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData ];
    [request setTimeoutInterval:30];
    NSString *aUrl = @"https:/myServer
    [request setURL:[NSURL URLWithString: aUrl ]];
    [request setHTTPMethod:@"PUT"];
    [request setValue:@"text/xml" forHTTPHeaderField:@"Content-type"];


    NSMutableData *postBody = [NSMutableData data];
    [postBody appendData:xmlData];
    [request setHTTPBody:postBody];
    NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration];
    NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate: self delegateQueue: nil];
    dispatch_semaphore_t semaphore = dispatch_semaphore_create(0);
     NSURLSessionDataTask *dataTask = [defaultSession dataTaskWithRequest:request completionHandler:^(NSData *taskData, NSURLResponse *taskResponse, NSError *taskError) {
     dispatch_semaphore_signal(semaphore);
     }];
    [dataTask resume];
    dispatch_semaphore_wait(semaphore, DISPATCH_TIME_FOREVER);
    if (dataTask.error == nil)
    {
        NSHTTPURLResponse* httpResponse = (NSHTTPURLResponse*)dataTask.response;
        int code = (int)[httpResponse statusCode];
        if(code == 200)
        {
            NSLog(@"%@", @"OK");
        }
        else
        {
            NSLog(@"%d", code);
        }
    }
    else
    {
        NSLog(@"%@", dataTask.error);
    }

The data is stored correctly to the Server but the DataTask returns the error 1005 "The network connection was lost."

I tried to analyse the Response (by enabling CFNETWORK_DIAGNOSTICS) from and I have seen, that the Response retunes with code "200 The request completed successfully."

You can find the protocol (beginning from the Response part)

Thanks

Paul
