这是一个非常奇怪的问题,与我们网络中运行 Windows 10 的一台(且唯一)特定 PC 有关。
这台电脑无法打开这两个网页:https://www.chces-soutezit.cz和https://toulcuvdvur.cz(暂停)
为什么奇怪呢?
- 这两个 URL 在其他地方都可以正常工作。
- 当连接到其他 PC 时,它们确实在同一根 UTP 电缆上工作。
- 该问题与登录用户无关(相同
ERR_TIMED_OUT
) ping
,tracert
并且nslookup
一切运行正常。wget
或者 powershell 等效程序也不起作用。- (是的,其他页面比如https://seznam.cz工作得很好)
- 暂时禁用防火墙:没有运气。
- 启动到 Windows 安全模式:没有运气。
- 为了确保万无一失,我们甚至在那里重新安装了 MS Windows(!),执行了所有更新...:没有运气。
- 凶手来了:两者当 GNU/Linux live 发行版启动时,页面在同一台机器上正常工作(是的,什么鬼?!)
