UnreachableBrowserException when implicitlyWait > 60s

[mmajcherczyk]

🐛 Bug Report

UnreachableBrowserException instead of NoSuchElementException when implicitlyWait greater than 60s

To Reproduce

run this test(selenium 4.0.0-alpha-5)

@Test
public void test() {
    WebDriverManager.chromedriver().setup();
    ChromeOptions options = new ChromeOptions();
    WebDriver driver = new ChromeDriver(options);
    driver.manage().timeouts().implicitlyWait(61, TimeUnit.SECONDS);
    driver.get("https://google.com");
    driver.findElement(By.id("identifierId"));
    driver.quit();
}

I get an error message:

org.openqa.selenium.remote.UnreachableBrowserException: Error communicating with the remote browser. It may have died.

Expected behavior

I am expecting an error: NoSuchElementException

when implicitlyWait less than 60 second is ok, I get NoSuchElementException

This is likely an issue in Chromedriver not keeping the connection open for long enough. Please raise an issue with the ChromeDriver team

Please log chromedriver issues with the chromedriver project.

https://sites.google.com/a/chromium.org/chromedriver/help

Please be sure to include a completely reproducible test script for them, without a way to reproduce the issue you are seeing there is no good way for them to fix the problem. A reproducible test script includes a WebDriver script and a link to the page in question. If you can not provide a link, create one using jsfiddle.net

@AutomatedTester it's not the chromedriver fault. I have the same error on firefox

in selenium 3.141.59 the problem does not occur

[AutomatedTester]

This is likely hitting a HTTP client hitting a timeout after 1 minute.

[mkozachenko]

I am also getting this error when test tries to open URL that does not respond for 1 minute

[Buddy119]

This error does not occur on my side.

@mmajcherczyk you can try to upgrade your browser version

It seems that chrome option "--no-sandbox" helps to get rid of this problem. I had this error for about 6 months until I found some years old post on StackOverflow with this very easy fix and it worked. I hadn't seen this exception for almost 2 months.
@Buddy119 I got this error most of the times when the very first call of driver.get("web url") did not load anything for less then 60 seconds. Webpage has to just wait for response and not give response of any kind. You can try to emulate this with local proxy throttling - I did it with BrowserMobProxy method setLatency()

The fix linked on the commit above should be available in the next beta, ~1 week from now.
