我正在尝试使用URLSession执行数据任务,当我在iOS11设备(iPhone 5S)上运行它时出现控制台错误:

2017-09-22 15:22:17.942015-0300 app[1355:283536] TIC TCP Conn Failed [3:0x1c417af40]: 1:61 Err(61) 
2017-09-22 15:22:17.943698-0300 app[1355:283536] Task <A32F0275-75C3-4F64-AB92-2E37527AB813>.<0> HTTP load failed (error code: -1004 [1:61])

                          nil];

    NSString *path = @"fotoCartao";
    NSData* params = [NSJSONSerialization dataWithJSONObject:parameters options:0 error:nil];
    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@%@", kEcardURL, path]];
    NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url];
    [urlRequest setHTTPMethod:@"POST"]; …
