组织。openqa。硒。WebDriverException:与Selenium Geb GeckoDriver和Firefox的连接被拒绝

在安装了Mozilla Firefox 60.4.0的Linux机器上运行测试时,我随机遇到了这个错误“org.openqa.selenium.WebDriverException:连接被拒绝”。

我尝试的不同组合是:

1) 硒3.12.0 geb斯波克:2.1 壁虎河0.18.0

2) 硒3.12.0 geb斯波克:2.1 壁虎河0.23.0

3) 硒3.14.0 geb斯波克:2.1 壁虎河0.23.0

我甚至试着将xvfb显示器的偏移量设置为5。 此外,还检查了geckodriver和firefox的卸载情况。没有这样的失效过程。

有没有办法尝试捕获这个“org.openqa.selenium.WebDriverException:连接被拒绝”,然后再次尝试创建驱动程序?有人知道为什么会发生这种错误,以及如何解决这个问题吗?
