'Unable to create new session.' error using selenium-server-standalone-3.9.1.jar with ChromeDriver and Chrome

Question

For the past few days, I was running tests using Selenium WebDriver with no issues. However, even though I didn't change anything in the code or my system, the last few times I tried to create a new browser session, I always get the following error: Link

This happens regardless of whether I try to create a session through code, or manually through the browser.

This is the result of running the Selenium server and three tests:

I've tried downgrading, reinstalling everything, but nothing seems to work.

What I'm using:

Ubuntu 18.04
Selenium Java Server 3.9.1
Chrome 73
Chrome Driver 74

Also, oddly enough, my colleague who similarly is working on Selenium with me, is now running into the exact same issue on their own system.

This error message...

...implies that your ChromeDriver version is chromedriver=2.41

Your main issue is the incompatibility between the version of the binaries you are using as follows:

You are using chromedriver=2.41
Release Notes of chromedriver=2.41 clearly mentions the following :

Supports Chrome v67-69

Presumably you are using the latest GAed chrome=73.0
Release Notes of ChromeDriver v2.46 clearly mentions the following :

Supports Chrome v71-73

So there is a clear mismatch between ChromeDriver v2.41 and the Chrome Browser v73.0

Solution

Upgrade ChromeDriver to current ChromeDriver v2.46 level.
Keep Chrome version between Chrome v71-73 levels. (as per ChromeDriver v2.46 release notes)
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
Execute your @Test.

Thanks for your response, it played a big role in helping us find a solution. The only part that was missing was that we needed to update our Selenium server version as well. Sorry for the late answer, and thanks again. Cheers! — zzzz4, Apr 23 '19 at 23:48
@zzzz4 In your question heading you have explicitly mentioned about **Selenium Java Server 3.9.1** which should work as per my solution. Hence the answer. Else I would have suggested to upgrade to recent _Selenium v3.141.59_ as a generic suggestion. Glad to know your issue got resolved. Good luck. — DebanjanB, Apr 24 '19 at 06:26
