The "DNS_PROBE_FINISHED_NXDOMAIN" error message typically indicates that the domain name requested could not be resolved by the DNS (Domain Name System). This means that the server was unable to find the IP address associated with the domain name, potentially because the domain name does not exist or there is a problem with the DNS server.
It could be a problem with your internet connection, your DNS server, or the website's server. You can try troubleshoot like restarting your router, flushing your DNS cache, changing your DNS servers, or contacting the website's administrator.
Try these troubleshooting steps in this order, and stop once the website starts working.
1. Restart your router
Disconnect power to router for 30 seconds and reconnect.
2. Flush your DNS Cache
Flush your DNS Cache on Windows
To flush the DNS cache on Windows, you can use the command prompt. Here's how:
Press the Windows key + X and select "Command Prompt (Admin)" from the menu.
Type the command "ipconfig /flushdns" and press Enter.
You should see a message that says "Windows IP Configuration: Successfully flushed the DNS Resolver Cache."
Alternatively, you can also use the Windows PowerShell with administrative rights and run the command "Clear-DnsClientCache"
It is important to note that, flushing the DNS cache will clear all the stored DNS lookups on your computer, it will not affect any of your personal settings or files.
Flush your DNS Cache on macOS
To flush the DNS cache on macOS, you can use the Terminal application. Here's how:
Open the Terminal application, which can be found in the Applications > Utilities folder or by searching for it in Spotlight.
Type the command "sudo dscacheutil -flushcache" and press Enter.
You will be prompted to enter your admin password. Once you've entered your password, press Enter again.
You should see a message that says "dscacheutil: cache flush completed."
Alternatively, you can also use the command "sudo killall -HUP mDNSResponder"
3. Change your DNS servers
This can be done at the browser, computer or router level.
