Webdriver exception: "chrome not reachable" - selenium-webdriver

Question

I am running selenium test cases in a ubuntu server which basically runs testcases in both firefox and chrome.
Firefox launches and test cases run successfully but chrome throws exception:
*****below is the snippet of the stacktrace:*****
Starting ChromeDriver (v2.8.240825) on port 21549
PAC support disabled because there is no system implementation
Test IntegrationTest.AdminUserelementscheck failed:
org.openqa.selenium.WebDriverException: chrome not reachable
(Driver info: chromedriver=2.8.240825,platform=Linux 2.6.32-431.el6.x86_64 x86_64) (WARNING: The server did not provide any stacktrace information)
[error] Command duration or timeout: 20.83 seconds
Hi Below is the small snippet of my code :
public class IntegrationTest {
private static final String configFile="test.properties";
private final String FIREFOX="firefox";
private final String CHROME="chrome";
private final String PHANTOMJS="phantomjs";
private final String BROWSERNAME="browser";
private static Properties props = new Properties();
public WebDriver webDriver;
private static Configuration additionalConfigurations;
#BeforeClass
public static void setUp() throws IOException, SQLException{
props.load(IntegrationTest.class.getResourceAsStream("/" + configFile));
}
#test
public void AdminUserelementscheck() throws SQLException, IOException {
String[] browsers = props.getProperty(BROWSERNAME).split(",");
System.out.println("Number of browsers specified in conf:"+props.getProperty(BROWSERNAME));
for(String browser:browsers){
System.out.println("Browser currently processing:"+browser);
if(browser.equalsIgnoreCase(FIREFOX))
webDriver = new FirefoxDriver();
else if(browser.equalsIgnoreCase(CHROME))
webDriver = new ChromeDriver();
else
webDriver = new PhantomJSDriver();
running(testServer(3333,fakeApplication()),webDriver, new Callback<TestBrowser>() {
********* LOGIN AND ASSERTION STATMENTS*******************
browser.quit()
}
});
}

Answer 1

This would be because Chrome is also making use of unix containers in order to run. If you want this to run within docker, pass the docker run command
--privileged
Otherwise you can start Chrome with
--no-sandbox

Answer 2

I have encoutered similar problem. I am running my Selenium tests locally and "webdriver exception chrome not reachable" error suddenly showed up.
The problem was that I already had too much tabs in my regular chrome browser. After getting frustrated I have closed few tabs and suddenly it worked. I am not sure if there is a certain limit of tabs, but if somebody encounters same problem, give it a try.

Your chrome driver seems to be old. Try downloading latest as of date from below and report back if you get any new errors.
http://chromedriver.storage.googleapis.com/index.html?path=2.14/

Answer 4

Also ensure that PATH environment variable has the path to chromedriver.
