Flush DNS Cache on Your Computer
To flush the DNS cache on your computer, follow these steps:
Open the Command Prompt. You can do this by searching for "cmd" in the Start menu or by pressing the Windows key + R and then typing "cmd" and pressing Enter.
In the Command Prompt, type the following command: ipconfig /flushdns and press Enter.
You should see a message that says "Successfully flushed the DNS Resolver Cache." This means that the DNS cache has been flushed and your computer will now use the most up-to-date DNS information.
Close the Command Prompt and try accessing the website that you were having issues with. It should now be accessible.
Keep in mind that flushing the DNS cache may only temporarily fix the issue and the problem may return in the future. In that case, you may need to troubleshoot the issue further to find a more permanent solution.
