How to Clear Chrome DNS Cache (to fix DNS PROBE FINISHED NXDOMAIN error).
To clear the DNS cache in Google Chrome and potentially fix the DNS PROBE FINISHED NXDOMAIN error, follow these steps:

1. Clear Chrome’s DNS Cache:
Open Google Chrome.
In the address bar, type `chrome://net-internals/#dns` and press Enter.
On the page that opens, click the "Clear host cache" button. This will clear the DNS cache in Chrome.

2. Flush the System DNS Cache (if needed):
If the problem persists, you may need to flush the DNS cache on your computer as well. Here’s how to do that:

For Windows:
Press Win + R to open the Run dialog box.
Type `cmd` and press Enter to open the Command Prompt.
In the Command Prompt window, type the following command:
ipconfig /flushdns
Press Enter. You should see a message saying, "Successfully flushed the DNS Resolver Cache."

For Mac:
Open the Terminal app (you can find it by searching in Spotlight).
Type the following command and press Enter:
sudo killall -HUP mDNSResponder
You may be prompted for your administrator password. Type it and press Enter.
The system will flush the DNS cache.

For Linux:
Open a terminal window.
Run the following command:
sudo systemd-resolve --flush-caches
You may need to enter your password to complete the action.

3. Restart Chrome and Your Computer:
After clearing both Chrome’s DNS cache and your system’s DNS cache, restart Google Chrome and, if necessary, restart your computer to ensure that all settings are refreshed.

4. Additional Troubleshooting (if needed):
If the issue persists after clearing the cache, consider these additional troubleshooting steps:
Check your DNS settings: Make sure you're using a reliable DNS server. You can switch to public DNS servers like Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1 and 1.0.0.1).
Restart your router: Sometimes, a router’s DNS cache might cause the issue. Unplugging and restarting the router may resolve the problem.
Check your network connection: Make sure your internet connection is stable and that you're connected to the correct network.

By clearing both Chrome's DNS cache and your system’s DNS cache, you should be able to resolve most DNS PROBE FINISHED NXDOMAIN errors.
