First, test the network connection. Verify that your device is connected to the wifi or wired internet. Also, check if there is a yellow exclamation sign next to the network icon.

If the test fails, try to diagnose the issue by opening the Command Prompt by typing cmd in the search bar. Then, type ipconfig /all and see if the DNS settings are correct.

To effectively flush the DNS, open the command prompt again and type ipconfig /flushdns. Then, type netsh winsock reset and reboot the system for the changes to take effect.

Turn off all unnecessary programs, such as firewalls and antivirus software, to avoid conflicts that prevent website access.
