GitHub user dosubot[bot] added a comment to the discussion: Can't diplay Thumbnail dashboard and chart?
<!-- Answer --> I found a similar unsolved discussion that might be relevant to your issue: [Superset 4.0.2: The REST API for thumbnail download is not working](https://github.com/apache/superset/discussions/30988) <sup>[[1]](https://github.com/apache/superset/discussions/30988)</sup>. For your current setup, ensure the following: 1. **Redis Configuration**: Verify that your Redis server is running and accessible at the specified host and port. Connection issues with Redis can prevent thumbnails from being cached or retrieved properly <sup>[[2]](https://github.com/apache/superset/blob/master/tests/integration_tests/superset_test_config_thumbnails.py)</sup>. 2. **Playwright Setup**: Ensure that Playwright and the necessary browser dependencies are correctly installed. This includes running `playwright install-deps` and installing the required browsers (e.g., `playwright install chromium`) <sup>[[3]](https://github.com/apache/superset/blob/master/Dockerfile)</sup>. 3. **WEBDRIVER_BASEURL**: Make sure that the `WEBDRIVER_BASEURL` is correctly configured and accessible from the worker environment. If there are issues with the URL or authentication, it can prevent the worker from generating thumbnails <sup>[[4]](https://github.com/apache/superset/blob/master/docs/docs/configuration/alerts-reports.mdx)</sup>. 4. **Feature Flags**: Double-check that all necessary feature flags are enabled in your configuration, as you have done. This includes `THUMBNAILS`, `THUMBNAILS_SQLA_LISTENERS`, `ENABLE_DASHBOARD_SCREENSHOT_ENDPOINTS`, and `ENABLE_DASHBOARD_DOWNLOAD_WEBDRIVER_SCREENSHOT` <sup>[[5]](https://github.com/apache/superset/blob/master/superset/config.py)</sup>. If these configurations are correct and the issue persists, consider checking the logs for any error messages that might provide more insight into the problem. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
