What troubleshooting steps should I follow if I experience connectivity or loading issues in Chrome after configuring Cloudflare 1.1.1.1 DNS?

If you encounter connectivity or loading issues in Chrome after setting up Cloudflare 1.1.1.1 DNS, try these troubleshooting steps: 1. **Flush DNS Cache:** Clear your operating system's DNS cache. On Windows, open Command Prompt as administrator and type `ipconfig /flushdns`. On macOS, open Terminal and type `sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder`. Also, clear Chrome's internal DNS cache by going to `chrome://net-internals/#dns` and clicking "Clear host cache." 2. **Clear Browser Cache & Cookies:** In Chrome, go to `chrome://settings/clearBrowserData` and clear cached images, files, and cookies. 3. **Temporarily Revert DNS:** Change your DNS settings back to your ISP's defaults or to a well-known alternative like Google DNS (8.8.8.8 and 8.8.4.4). If the problem resolves, the issue is likely with the Cloudflare DNS configuration. 4. **Check Router Settings:** If you configured DNS on your router, ensure the settings were saved correctly and restart the router. 5. **Disable Chrome's Secure DNS:** If you're using Chrome's built-in Secure DNS, try disabling it temporarily (`chrome://settings/security`) to see if it's causing a conflict. 6. **Verify Network Connectivity:** Ensure your internet connection is generally working by testing on another device or using another browser.
