不同的网络会导致 UnreachableBrowserException 异常吗？

Question

我有两个网格设置

1. 本地网格设置（集线器和节点在我的本地机器上运行）和我的local machine 连接到network#1

2. VM 网格设置（集线器和节点在我的虚拟机中运行）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）但是如果我将network#2 IP address （VM IP 地址）传递给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？

Answer 1

是的，由于防火墙而发生异常。 ping test 从本地机器到 VM 成功但不是从 VM 到本地。我联系了组织网络管理员并确认了这一点。
