<!-- Answer --> The HTTPConnectionPool ReadTimeoutError when taking a screenshot in Superset reports is often related to Selenium WebDriver timing out while waiting for the page or elements to load. This can be caused by slow rendering, insufficient resources, or suboptimal WebDriver configuration. Recent discussions and code changes suggest several steps to address this: - Increase the timeout durations in your superset_config.py by setting `SCREENSHOT_LOCATE_WAIT = 30` and `SCREENSHOT_LOAD_WAIT = 60` to give Selenium more time to find and load elements before timing out. This has helped resolve similar timeout issues for others [[discussion](https://github.com/apache/superset/discussions/31464)]. - Ensure your Selenium WebDriver is configured with recommended options in superset_config.py, such as: ```python WEBDRIVER_TYPE = 'chrome' WEBDRIVER_OPTION_ARGS = [ '--headless', '--no-sandbox', '--disable-gpu', '--disable-dev-shm-usage', '--disable-setuid-sandbox', '--start-maximized' ] ``` These options help with stability and performance in headless environments [[discussion](https://github.com/apache/superset/discussions/31464)]. - Make sure your environment has enough memory and that the WebDriver has the necessary permissions to run. - There was a recent change to how Superset waits for elements when taking screenshots, which may affect timing and reliability [[changelog](https://github.com/apache/superset/blob/master/superset-frontend/CHANGELOG.md)]. If you continue to see timeouts, check for any resource constraints (CPU/memory) on your server, and review the full logs for any additional clues. If you are running Superset and Selenium in containers, ensure network connectivity between them.
