an error on the server ("unable to decode an event from the watch stream: http2: client connection lost") has prevented the request from succeeding

我执行CronJob：

kubectl get pods -n kube-backup -w

处理的时间比较长，突然报了如下错误：

STATUS                       REASON          MESSAGE
Failure                      InternalError   an error on the server ("unable to decode an event from the watch stream: http2: client connection lost") has prevented the request from succeeding

请问是什么原因，我该如何解决？
