The TCP connection for the watch was disconnected

[jakub88]

My application listens to a key in etcd, but after a period of time (about a week) without any data transmission, the TCP connection was dropped, and the etcd client did not automatically reconnect, causing my application to miss the key change events. After I restarted my application, the watch resumed working normally. How should I troubleshoot this issue?

Below is my client initialization configuration.
clientV3.Config{ Endpoints: etcdEndpoints(), DialTimeout: 5 * time.Second, TLS: tlsConf, },

I couldn't reproduce it. I tried to even restart etcd cluster, the client side watch can still continue to work.
