    No informative Error message. Only a timeout exception when navigate() is called on the driver:
    org.openqa.selenium.TimeoutException: timeout
  • Fix:
    options.addArguments("--proxy-server='direct://'");
options.addArguments("--proxy-bypass-list=*");
• Chrome is very slow in headless mode
  • Fix:
    options.addArguments("--proxy-server='direct://'");
options.addArguments("--proxy-bypass-list=*");
• Chrome does not operate correctly after a certain time, when tests run very long resp. many actions are executed in one test session
