Same issue found on windows 7 node as well

[Andro72]

It is because it is used \tmp \webdriver\3.12.0.jar
WARNING: Selenium 3.7.1 is the oldest compatible version with Selenium-Grid-Extras 2.x. Downgrade to Selenium-Grid-Extras 1.x if you would like to use an older version of webdriver.
In selenium_grid_extras_config.json

"auto_update_drivers": "0",
"webdriver": {
  "version": "3.7.1"
},

@Andro72
3.12.0 is higher version than 3.7.1
"auto_update_drivers": "1", "webdriver": { "version": "3.12.0" },
should be valid configuration since driver version 3.11.0 works absolutely fine.

I am having the same issue. I had to edit my config to not auto update the webdriver and set it to 3.11.0 and I could get the node up and running after restarting the Hub.

I face the same issue since moving on driver 3.12.0.
Staying on 3.11.0 is ok.

[gwynjudd]

I changed the following to get it working (was 3.12.0):

    "auto_update_drivers": "0",
    "webdriver": {
      "version": "3.11.0"
    },

[shankarkc]

Yes. I too hit this issue. I am using 3.14.0 webdriver.

[shankarkc]

it looks like its because of SeleniumHQ/selenium#6275

[shankarkc]

It looks like there are other bugs too to use latest selenium. I modified the code to remove the custom section. I still see extra proxy having issues. Just by removing custom grid extra will not work😥
