我有硒電網3.0.1設置有一個輪轂和三個節點如下：硒網格路由錯誤的節點
- 第一個節點：與Linux的Chrome和Firefox
- 第二個節點：視窗10使用Chrome，火狐，邊緣和Internet Explorer
- 第三結點：Linux中Appium與Android模擬器
運行出於某種原因，網格不智能選擇節點基於平臺和b rowser。
我特別有IE和Appium的問題。
我開始集線器：
nohup java -cp selenium-video-node-2.1.jar:selenium-server-standalone-3.0.1.jar org.openqa.grid.selenium.GridLauncherV3 \
-servlets com.aimmac23.hub.servlet.HubVideoDownloadServlet \
-role hub \
2>&1 > logs/hub.log &
我開始例如我的Linux節點，具有：
nohup java -Dwebdriver.chrome.driver="/home/ubuntu/testcloud/webdrivers/chromedriver" \
-Dwebdriver.chrome.bin="/usr/bin/opera" \
-Dwebdriver.chrome.logfile="/home/ubuntu/testcloud/logs/chrome.log" \
-Dwebdriver.gecko.driver="/home/ubuntu/testcloud/webdrivers/geckodriver" \
-Dwebdriver.firefox.bin="/home/ubuntu/testcloud/browsers/firefox/firefox" \
-Dwebdriver.firefox.logfile="/home/ubuntu/testcloud/logs/firefox.log" \
-cp selenium-video-node-2.1.jar:selenium-server-standalone-3.0.1.jar org.openqa.grid.selenium.GridLauncherV3 \
-servlets com.aimmac23.node.servlet.VideoRecordingControlServlet -proxy com.aimmac23.hub.proxy.VideoProxy \
-role wd -hub "http://172.31.1.65:4444/grid/register/" \
2>&1 > logs/selenium.log &
我配置驅動程序，在用Python：
d=DesiredCapabilities.INTERNETEXPLORER.copy()
d['loggingPrefs']={ 'browser': 'ALL' }
d["platform"]="WINDOWS"
driver = webdriver.Remote(
command_executor="http://"+HUB+":4444/wd/hub",
desired_capabilities=d
)
driver.maximize_window()
driver.implicitly_wait(30)
當我使用此配置運行測試，每3次中有2次，其他節點以類似方式響應：
Traceback (most recent call last):

任何人都可以幫我解決這個問題嗎？
