Own chrome browser not running

[William-67]

I try using my own browser, I set this up in my .env file:

CHROME_PATH="C:\Program Files\Google\Chrome\Application\chrome.exe" CHROME_USER_DATA="C:\Users\YourUsername\AppData\Local\Google\Chrome\User Data"

It open my chrome, but after then not running task at all, and no error occurred, just stuck in there.

I assume it may be due to multiple profile I have so I deleted all others but with main profile, but it still not working.

Set CHROME_USER_DATA empty, try again

Now CHROME_USER_DATA is empty, an error occurs after running:

[src.browser.custom_browser] Failed to start a new Chrome instance.: BrowserType.connect_over_cdp: connect ECONNREFUSED ::1:9222
Call log:

Check if there is a process occupying port 9222. If you are using Windows, enter the following command in the terminal: netstat -aon|findstr 9222. Then, run taskkill /f /pid {pid of 9222}.

Did anyone find the solution for this issue?

In case it helps anyone (in windows), I created a .bat file, like so: @echo off "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Profile 16" %*

And then set my path to CHROME_PATH=C:\Users\user\web-ui\my-chrome.bat

This way I'm able to have it load the exact profile I want to load.

@alexisCode50 I also encountered this problem, my application scenario is localized Ollama, the model is deepseek. I found that using vision with uncheck off worked just fine. So I guess because the model doesn't support vision, or when you use something like a model that doesn't support vision, Error will be displayed。Hope this helps you...

Checking the "Use Own Browser" box in web ui is not working, no errors but when I enter my profile path in CHROME_USER_DATA, it gives following error:

ERROR [browser] Failed to initialize Playwright browser: BrowserType.launch: Pass user_data_dir parameter to 'browser_type.launch_persistent_context(user_data_dir, **kwargs)' instead of specifying '--user-data-dir' argument

I think it's something to do with deprecation stuff, I tried to tinker a bit, managed to get rid of the error but the browser launched was still not the profile I want it to load from CHROME_USER_DATA.

I'm having this same issue. I've tried disabling vision, trying using my own browser and not using my own browser. I also tried python 3.11 and 3.13, as well as the .venv method and the docker method. All led to the same issue. I was testing this on Windows 11. I'm going to try on my linux vm to see if the issue is the same.

Same problem on Ubuntu. Both times I filled in the "CHROME_PATH" setting, but not "CHROME_USER_DATA"

Same issue here on Windows
