WebDriverException: unknown error: DevToolsActivePort file doesn't exist while trying to initiate Chrome Browser

Question

I am trying to launch chrome with an URL, the browser launches and it does nothing after that.

I am seeing the below error after 1 minute:

Unable to

Since this is the most active message for this type of error, I wanted to mention my solution (after spending hours to fix this).

On Ubuntu 18.04, using Chrome 70 and Chromedriver 2.44, and Python3 I kept getting the same DevToolsActivePort error, even when I disabled all options listed above. The chromedriver log file as well as ps showed that the chromedriver I set in chrome_options.binary_location was running, but it always gave DevToolsActivePort error. When I removed chrome_options.binary_location='....' and add it to webdriver creation, I get it working fine. webdriver.Chrome('/path to ... /chromedriver',chrome_options=chrome_options)

Thanks everybody for your comments that make me understand and resolve the issue.
