所以我有一个硒集线器和一些节点。ESXi 上的两个 Windows 10 虚拟机（A和）。B
B克隆自A，因此除了 IP 和主机名外，它们的配置相同。
A有一个节点，工作正常。
B有一个节点，但是集线器无法获取它的状态，所以我首先使用了一个固定端口并重新启动了节点，但我无法通过http://win10-b:16050/status.
我允许 Java 通过防火墙访问，甚至暂时禁用了两个防火墙（集线器和节点），但无济于事。
这是节点：

这是集线器，拼命地试图保持连接：

任何提示我可能在这里遗漏的内容，总共 10 个节点，这是唯一一个有问题的节点（不过，除了AWindows 7 之外的其他节点）。
