java - java.net.SocketException:DNS刷新后无法解析的地址

今天早上我的DNS崩溃了，我不得不刷新所有DNS条目并将该域指向正确的IP。此后，我所有的Apache服务和其他服务都按预期恢复。不过不是我的Java服务器，它在DNS崩溃之前没有任何问题。

现在，每次我尝试运行Java服务器时，都会出现以下错误：

在应用程序的控制台中，出现以下错误：

WebSocket connection to 'wss://app.domain.com:8081/' failed: Error in connection establishment: net::ERR_CONNECTION_TIMED_OUT

任何帮助与此非常感谢。

最佳答案

大约15-20小时后，Java服务器开始正常连接并且不再发出Unresolved address错误，这似乎是DNS传播问题。
