Only local connections are allowed Chrome and Selenium webdriver

Question

I am using Chrome webdriver 2.23 & Selenium 2.53.1 I have tried a lot but could not come to the fix for this issue that whenever I run my selenium script it is giving me an error

Starting ChromeDriver 2.23.409699 (49b0fa931cda1caad0ae15b7d1b68004acd05129) on port 12162

Only local connections are allowed.

Answer 1

This is just an informational message. Your issue might be because of the mismatch between the versions of chrome driver and selenium-server-standalone.

Try with the newest selenium version 3.0, it's working for me.

Please, note that for selenium 3.0 you would like to specify the driver 1st and then after the selenium server.

With the new selenium, which is 3.0 you must use:

java -Dwebdriver.chrome.driver=path_to_chrome_driver -jar selenium-server-standalone-3.0.0-beta2.jar

If you are using selenium version below 3.0 you need to reverse the order of selenium with the driver, like: 

java -Dwebdriver.chrome.driver=path_to_chrome_driver -jar selenium_server.jar

When you are starting the selenium server, open a console within the directory with the chrome driver and selenium server and execute this above the command.

Basically, the message “only local connections are allowed” usually appears in chrome when we are starting a chromedriver instance with selenium webdriver.This message is not an error but this is just a security check by chromedriver.
