我上周通过 Contabo 租用了一项 VPS 服务，以便可以在上面运行 Minecraft 服务器。
起初我安装了 Ubuntu 18.04，一切都运行正常，直到大约 2 天后，系统似乎更新了某些内容，导致我的网络出现故障。我尝试解决它，但没有找到问题，我再次重新安装了系统，但 2/3 天后又发生了同样的情况。所以我决定安装 Ubuntu 16.04，认为这可能是操作系统问题。安装后，它发生了完全相同的情况...
如果我尝试从我的电脑发送 ping，我会看到数据包的时间加倍，而且很多数据包都丢失了。FTP、SSH 和其他网络服务都无法正常工作。但幸运的是，我可以提取系统日志日文件。18:48 是一切开始崩溃的时刻，我会尽可能简短地粘贴在这里：

这是 /etc/network/interfaces 文件：
您可能会看到不同文件的主机名不同，这是因为我认为更改它可能是解决方案之一。
提前感谢你的帮助。我真的很想找到问题所在……
此致！
