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 get it fixed. Whenever I run my selenium script, it is giving me the following err

Answer 1

This is just an informational message. Your issue might be a missmatch between the versions of chromedriver and selenium-server-standalone.

Try with the latest selenium version 3.0, it is working for me.

Please not that for selenium 3.0 you need to specify the driver first and after the selenium server.

With the new selenium, which is 3.0 you should 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 in the directory with chromedriver and selenium server and execute the above command.

Sorry for late post but still for info,I also facing same problem so I Used updated version of chromedriver ie.2.28 for updated chrome browser ie. 55 to 57 which resolved my problem.

Answer 3

I was able to resolve the problem by following steps: a. upgrade to the latest chrome version, clear the cache and close the chrome browser b. Download latest Selenium 3.0

Answer 4

I was also getting the same issue. I resolved this issue by updating the chromedriver. So if anyone is facing same issue with chrome browser just update your chromedriver.

Answer 5

1. Check the version of your installed Chrome browser.

2. Download the compatible version of ChromeDriver from

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

3. Set the location of the compatible ChromeDriver to:

    System.setProperty("webdriver.chrome.driver", "C:\\Users\\your_path\\chromedriver.exe");
   

4. Run the Test again.

It should be good now.

Answer 6

First off, What you are seeing is not an error. It is an informational message.

When you run this driver, it will enable your scripts to access this and run commands on Google Chrome.

This can be done via scripts running in the local network (Only local connections are allowed.) or via scripts running on outside networks (All remote connections are allowed.). It is always safer to use the Local Connection option. By default your Chromedriver is accessible via port 9515.

See this answer if you wish to allow all connections instead of just local.

If your Chromedriver only shows the above two messages (as per the question), then there is a problem. It has to show a message like this, which says it started successfully.

Starting ChromeDriver 83.0.4103.39 (ccbf011cb2d2b19b506d844400483861342c20cd-refs/branch-heads/4103@{#416}) on port 9515
Only local connections are allowed.
Please see https://chromedriver.chromium.org/security-considerations for suggestions on keeping ChromeDriver safe.
ChromeDriver was started successfully.

To troubleshoot this...

Step 1: Check your Chromedriver version

$ chromedriver --version

ChromeDriver 83.0.4103.39 (ccbf011cb2d2b19b506d844400483861342c20cd-refs/branch-heads/4103@{#416})

My version is 83.0.4103.39.

Step 2: Check your Chrome Browser version

Open Google Chrome.

Options --> Help --> About Google Chrome

Or open a terminal and run the following command (works on Ubuntu).

$ google-chrome --version

Google Chrome 83.0.4103.61

My version is: Version 83.0.4103.61

Step 3: Compare versions of Chromedriver and Google Chrome

Both these versions are starting with 83, which means they are both compatible. Hence, you should see a message like below, when you run the below command.

$ chromedriver 

Starting ChromeDriver 83.0.4103.39 (ccbf011cb2d2b19b506d844400483861342c20cd-refs/branch-heads/4103@{#416}) on port 9515
Only local connections are allowed.
Please see https://chromedriver.chromium.org/security-considerations for suggestions on keeping ChromeDriver safe.
ChromeDriver was started successfully. 

If your versions mismatch, then you will see the following message. You will not see the line which says, ChromeDriver was started successfully..

$ chromedriver

Starting ChromeDriver 80.0.3987.106 (f68069574609230cf9b635cd784cfb1bf81bb53a-refs/branch-heads/3987@{#882}) on port 9515
Only local connections are allowed.
Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.

Step 4: Download the correct version of Chromedriver

Download the correct version that matches your browser version. Use this page for downloads. After you download, extract the content, and move it to one of the following two folders. Open each of the following two folders and see whether your current Chromedriver is there. If it is on both folders, replace both. And do STEP 3 again.

/usr/bin/chromedriver
/usr/local/bin/chromedriver
