How to fix the DNS_PROBE_FINISHED_NXDOMAIN error?

On Windows you can find this file via the file explorer. First, open File Explorer and then find the Windows folder on your computer. It is usually located in the C: drive. Mac users can find the file in the / private / etc / hosts / folder.

Next go to System32 »Driver» etc.. Here you need to locate the hosts file and double click on it to open it. When prompted to choose an app, use Notepad.

Find the hosts file on your computer

Now check that the website address is in the hosts file. If it does, delete it along with the IP address next to it. Then save the file.
