Using Selenium in headless mode (without a visible browser window) significantly increases the likelihood of triggering Cloudflare's JavaScript challenges. Cloudflare is designed to detect and block headless browsers. While it's *possible* to configure headless browsers to mimic real browsers more closely, it's generally more reliable to run Selenium in a visible browser instance when dealing with Cloudflare.
