Help, I need to resolve this error: Exception: HTTPConnectionPool(host='browser-chrome', port=4444): Max retries exceeded with url: /wd/hub/session (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f71d4177650>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution')).

The Change Detection v0.52.7 application is running via Docker on a local machine with the Kali Linux OS.

but this is not quite right, you havent enabled anything... is this really your config?

[Julianamorpires]

I'll need to format the machine; other applications are showing errors. If that doesn't solve the problem, I'll reopen the discussion.
