webdriver.Chrome(...) call stuck on Jenkins

[Gabor Vuncs]

Hi There,

We are using Selenium (4.23.1) and latest chromedriver (127.0.6533.99) on Jenkins.
At webdriver.Chrome(...) call the test run is stuck.

Jenkins log:

Also tried with selenium 4.22.0, got the same result.

On local PC everything works properly.

What could be the problem?

Thanks in advance!

Suggestion: I would try to take it out of headless and watch what is does.  If it works, maybe try headless=old or headless=true to put it into the old version.  If it seems to be related, you may have discovered a bug, or possible a missing switch.  

Hope that helps.

Thanks for the tip!

I tried it with headless=old (Selenium 4.23.1 and latest chromedriver 127.0.6533.99) and it works on Jenkins.
On Jenkins no headless is not an option, but locally there were no problem with not headless / headless modes at all.
On Jenkins the tests are run in a docker, maybe this caused the freeze, locally we do not have time to try it in the docker.

If we have time we will try in docker and check it maybe we can see something.
