Why does the broswer not pop up?
Why does the broswer not pop up when running docker and localhost? Thanks.
What type of pop-up window? If it is a system pop-up window, it should not be supported.

@warmshao Shouldn't a Chrome or Chromium or some other browser pop up when one clicks on "Run Agent"?
i got the same problem, seems when docker only acce via VNC but then it show some flag errors so i went to direct install and works, trying to start local deepseek-r1:14b for second time with ollama, stopping and restartin is problematic, detection of properly executed task is also to be enhanced
I have problem logging to VNC thru docker, I can access it but it says wrong password.
@iulko have you found a solution to your problem?
I am facing a slightly different problem, that is: When running a browser-use agent in the web-ui I just get: "browser-use-webui-1 | 05/07/2025 19:56:54 webSocketsHandshake: unknown connection error" in the logs.

So the necessary services seems to be running and listening,
When trying to connect to the VNC within the browser, by opening http://localhost:6080/vnc.html?host=0.0.0.0&port=6080 and clicking on the "Connect" Button I just see: "Connecting...", with the accompanying loading bar - but nothing happens.
I am on fedora 42, with disabled SELinux (because starting that docker compose gave me SELinux errors).
