我试图在我设置的selenium hub上指出一些测试，并且我遇到了浏览器配置/功能的一些可能问题。
当我查看我在minikube中设置的Hub Pod的日志时，我看到以下消息（多次，测试脚本重试几次然后放弃并显示失败状态）

当我查看我的一个firefox pod的配置时，我看到以下内容：
Capabilities [{seleniumProtocol=WebDriver, acceptSslCerts=true, screen-resolution=1900x1880, tz=Greenwich, browserName=firefox, maxInstances=1, screenResolution=1900x1880, resolution=1900x1880, version=55.0.3, platform=LINUX}]
我想也许版本控制可能是我的问题，因为firefox pod是55.0.3，请求的功能显示47，但我不确定还有什么问题。我应该查看有关我的问题的更多详细信息？
作为参考，我的中心看起来像this
