不同的网络是否会导致 UnreachableBrowserException 异常？
Can different network be the cause for UnreachableBrowserException exception?
我有两个网格设置
本地网格设置（集线器和节点在我的本地机器上 运行ning）和我的 local machine 连接到 network#1
VM 网格设置（集线器和节点在我的虚拟机中 运行ning）和我的 virtual machine 连接到 network#2
当我执行脚本时，我需要将 IP address 作为参数传递。这里，
我可以通过传递 network#1 IP address 在本地机器上成功 运行 我的脚本（代码在本地机器上可用）但是如果我传递 network#2 IP address （ VM IP 地址）到 local machine 然后我得到以下异常，
org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
据我所知，集线器和节点应该连接到同一个网络。我们不能通过将 VM IP 地址 传递给 本地计算机 来 运行 脚本吗？
跟踪：
org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

是的，异常是由于防火墙造成的。 ping test 从本地机器到 VM 成功，但从 VM 到本地 失败。我联系了组织网络管理员并确认了这一点。
