Troubleshoot Playwright and Chromium startup
The Docker image uses the Playwright Python base image that matches the project requirement, so the browser binary and Linux dependencies arrive together.
01
If the browser will not launch
- Confirm the container was rebuilt after changing requirements.txt.
- Use headless mode in Docker unless a display server has been configured.
- Check that the image architecture matches the host runtime.
- Review the first browser-pool error before investigating later login failures.
02
If login fails instead
A browser launch success does not prove credentials or site access. Check the selected region, credentials, network access, and whether the site requested a CAPTCHA. Do not treat a CAPTCHA as a browser dependency problem.
