Twilio.Exceptions.ApiConnectionException：连接错误。任务已取消-Twilio C＃

Question

在获取特定日期范围内的录音时，我遇到了一个问题。我无法在本地重现该问题。 但是我在生产中不断遇到以下错误

“ Twilio.Exceptions.ApiConnectionException：连接错误：GEThttps：//api.twilio.com/2010-04-01/Accounts/AccountID/Recordings.json？DateCreated <= 2018-10-27T06：27：49Z- -> System.Threading.Tasks.TaskCanceledException：任务已取消。”

我们使用的代码在下面提到。该代码每2分钟运行一次

string accountSid = string.Empty;
string authToken = string.Empty;

  if (!string.IsNullOrEmpty(ConfigurationManager.AppSettings["TwilioAccountSID"]) && !string.IsNullOrEmpty(ConfigurationManager.AppSettings["TwilioAuthToken"]))
                    {
                        accountSid = ConfigurationManager.AppSettings["TwilioAccountSID"];
                        authToken = ConfigurationManager.AppSettings["TwilioAuthToken"];

                        TwilioClient.Init(accountSid, authToken);
                        var deleteDateRange = DateTime.UtcNow.AddDays(-1);
                        var recordings = RecordingResource.Read(
                                              dateCreatedBefore: deleteDateRange
                                            );

                        if (recordings.Count() > 0)
                        {
                            foreach (var recording in recordings)
                            {
                                RecordingResource.Delete(recording.Sid);
                            }
                        }
                    }
