服务器重启后一切正常。我能够连接到服务器。可能是什么问题，它只发生一次，我以前从未见过这样......相同的配置没有改变....

只要服务器端“不存在”，您的程序就会获得ConnectionTimeoutException。在大多数情况下，10秒（10000毫秒）的超时足以在任何进程之间进行连接，即使位于相隔很远的位置（高延迟）也是如此。

客户端无法建立连接的原因有很多：

  • 服务器进程未运行。
  • 服务器进程不接受连接。
  • 客户端进程用于连接的地址或端口不正确。
  • 到服务器的路由无效

通常，虽然这些会导致快速故障响应，因为服务器操作系统或某个路由器能够响应故障。以下是一些可能直接适用于您的情况：

  • 服务器物理关闭
  • 服务器或服务器进程挂起
  • 服务器与网络物理断开连接
  • 目的地址无效，网络上不存在该地址
  • 阻止来自客户端的传出路由的防火墙规则
  • 阻止传入服务器路由的防火墙规则

这些问题通常会导致超时异常，因为没有返回消息（客户端操作系统只需要放弃，这就是超时的原因）。

此列表可能不完整，但可以帮助您解决问题。如果您可以提供有关配置和网络的其他信息以及您希望帮助解决的问题，那么此处的某些人应该能够为您提供更具体的帮助。
