我已经在具有Windows操作系统的EC2实例上设置了Kinesis代理。对于在我的appsetting文件中指定的多个接收器，它使我收到以下错误。
这里可能出什么问题了，怎么办才能避免呢？
Amazon.KinesisTap.Hosting.LogManager错误KinesisFirehoseSink客户端 dev_dw_fh_s3_dl_inventtransorigin_snk例外： Amazon.KinesisFirehose.AmazonKinesisFirehoseException：签名 过期：20190610T083014Z现在早于20190610T092115Z （20190610T092615Z-5分钟）---> Amazon.Runtime.Internal.HttpErrorResponseException：远程服务器 返回错误：（400）错误的请求。 ---> System.Net.WebException： 远程服务器返回错误：（400）错误的请求。
此错误是随机发生的。似乎没有任何连接丢失的问题，因为它也在EC2实例上运行，时钟并不慢。
