&引用；org.openqa.selenium.WebDriverException:会话[4c1df58d0fbcc5da00e18fe779040941]因超时而终止；含硒铬酸盐

在Selenium网格中，我们一直面临浏览器超时问题。这种情况是间歇性的。我们找不到理由

如果有人有任何想法，那将是非常有帮助的

这在很大程度上取决于selenium网格配置。在配置json中可以看到，您使用了属性

maxSession

，请将其更改为

maxInstances

。您不应该限制网格上的最大会话数。即使你想保留这个财产，也要把它做成1000左右

同时消除属性

newSessionWaitTimeout

。让我们使用默认的配置值

---

因为我们知道，使用selenium网格的唯一问题是维护，因为它需要在集线器和节点的基础上定期重新启动。我建议使用一些第三方包装，以便更好、更易于维护。您可以通过groupon进行尝试。

我找到了解决此错误的方法。如果我们在脚本中使用driver.quit（），则此错误将消失。使用集线器和节点启动命令、跟踪日志以及完整的错误跟踪日志更新问题。@DebanjanB我已经完成了。请帮忙！1个等待插槽空闲的请求。功能{appActivity:my.yes.myyes4g.HomeActivity，appPackage:my.yes.yes4g，appWaitDuration:60，autoGrantPermissions:true，browserName:android，clearSystemFiles:true，deviceName:Altitude，fullReset:false，newCommandTimeout:60，noReset:true，noSign:true，平台：android，平台名称：android，版本：}hub的配置：browserTimeout:120 debug:false它现在一直这么说。请您提供帮助。请更新相关配置和最近的错误。很难理解评论中的当前配置。现在问题已经解决了。maxInstances设置为1。增加到5。然后这个错误发生了。谢谢，原因是什么？”我现在面临这个问题。更改该属性是如何解决的。
