[🐛 Bug]: Unable to establish websocket connection to http://x.x.x.x:4444/session/${session}/se/cdp

See original GitHub issue

What happened?

My objective is: to retrieve information in a xhr response body, sent by a submitted filled in form

My approach is: to use DevTools.

  1. locally, my approach is working
  2. remotely, my approach isn’t working indeed i have this exception 14:29:12 org.openqa.selenium.remote.http.ConnectionFailedException: 14:29:12 Unable to establish websocket connection to http://x.x.x.x:4444/session/${session}/se/cdp 14:29:12 Build info: version: ‘4.0.0’, revision: ‘3a21814679’ 14:29:12 System info: host: ‘c54d6a2a855f’, ip: ‘10.0.5.6’, os.name: ‘Linux’, os.arch: ‘amd64’, os.version: ‘3.10.0-1160.45.1.el7.x86_64’, java.version: ‘11.0.12’ 14:29:12 Driver info: driver.version: unknown

How can we reproduce the issue?

**DevTools**
Code to use DevTools
-----------------------
        WebDriver augmentedDriver= new Augmenter().augment(WebDriverRunner.getWebDriver());
        DevTools devTools = ((ChromeDriver) augmentedDriver).getDevTools();
        devTools.createSession();
        devTools.send(Network.enable(Optional.of(100000000), Optional.empty(), Optional.empty()));
        final String[] textFromResponseBody= new String[1];
        devTools.addListener(Network.responseReceived(), responseReceived -> {
            if (responseReceived.getResponse()
                                .getUrl()
                                .contains(PATH_CONTEXT)) {
                textFromResponseBody[0] = devTools.send(Network.getResponseBody(responseReceived.getRequestId()))
                                                           .getBody();
            }
        });

after the filling in the form
-----------------------------
        log.info("clickOnSubmit " + SUBMIT_BUTTON);
        SUBMIT_BUTTON.should(enabled, visible)
                     .click();

confirmation of extracting the responseBody
-------------------------------------------
         log.info("Work request ID : {}", textFromResponseBody[0]);

**NetworkInterceptor**
        final String[] textFromResponseBody= new String[1];
        NetworkInterceptor interceptor = new NetworkInterceptor(
                (((ChromeDriver)new Augmenter().augment(WebDriverRunner.getWebDriver()))),
                (Filter) next -> req -> {
                    HttpResponse res = next.execute(req);
                    if ( req.getUri().contains(PATH_CONTEXT)) {
                        log.info(res.getContentString());
                        textFromResponseBody[0] = res.getContentString();
                    }
                    return res;
                }
        );

Well, a Grid should not be exposed to the internet… There is a way to set a user and a password https://www.selenium.dev/documentation/grid/configuration/cli_options/#router

After reading again, the issue is that the connection to the websocket cannot be done because it is attempted with the internal docker container IP. To avoid that, please check how to set the Grid url in docker-selenium.
