Steps to reproduce the problem

1. Install Chrome
2. Run: "C:\Program Files\Google\Chrome\Application\chrome.exe" --remote-debugging-address=127.0.0.1 --remote-debugging-port=9222
3. Open multiple tabs (any content will do but the following list works for me):

In a Java application, run:

	System.setProperty("webdriver.chrome.verboseLogging", "true");
	ChromeOptions options = new ChromeOptions();
	options.setExperimentalOption("debuggerAddress", "localhost:9222");
	ChromeDriver client = new ChromeDriver(options);

5. The Java application will log the following and then hang:

11:49:33.511 [main] INFO io.github.cowwoc.capi.core.Browser.connectToChrome() - Connecting to 127.0.0.1:9222 11:49:33.513 [main] INFO io.github.cowwoc.capi.core.Browser.connectToChrome() - Options Capabilities {browserName: chrome, goog:chromeOptions: {args: [], debuggerAddress: 127.0.0.1:9222, extensions: []}} 11:49:34.036 [Forwarding newSession on session null to remote] DEBUG o.o.selenium.remote.RemoteWebDriver.log() - Executing: newSession [null, newSession {capabilities=[Capabilities {browserName: chrome, goog:chromeOptions: {args: [], binary: C:\Program Files\Google\Chr..., debuggerAddress: 127.0.0.1:9222, extensions: []}}]}] 11:49:34.037 [Forwarding newSession on session null to remote] DEBUG o.o.s.remote.service.DriverService.start() - Starting driver at C:\Users\USERNAME.cache\selenium\chromedriver\win64\134.0.6998.165\chromedriver.exe with [--port=27672, --log-level=ALL] 11:49:34.110 [JdkHttpClient-0-0] DEBUG o.o.s.remote.http.jdk.JdkHttpClient.execute0() - Executing request: (POST) /session

6. If you manually navigate from one tab to the next, across all tabs, ChromeDriver will unblock. It seems to be waiting for an event that never happens without manual intervention.

Problem Description

ChromeDriver hangs trying to connect to an existing browser. Because the hang occurs before the connection is established and the process needs to be fully automated, there is no known workaround.

Summary

ChromeDriver hangs connecting to an existing browser with open tabs
