How to Fix 'DNS Probe Finished NXDOMAIN' Errors When Accessing Business Websites in Brisbane

If you see a DNS_PROBE_FINISHED_NXDOMAIN error in your web browser, your computer cannot translate the website address into an IP address. This means the website cannot load, even if your internet connection is otherwise working normally. This guide walks Brisbane small business customers through the steps to resolve this error.

Quick Fix Steps

1. Refresh the webpage by pressing F5 or Ctrl + R.
2. Try opening the website in a different browser.
3. Restart your modem or router by switching it off, waiting 30 seconds, and switching it back on.
4. Clear your browser cache and cookies.

sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

3. Enter your Mac administrator password when prompted and press Enter.
4. Restart your web browser and try accessing the website again.

4. Set the time range to All time.
5. Click Clear data or Clear now.

Troubleshooting

Check if the Website is Down for Everyone

Before spending more time on your own network, confirm the website is actually online. Visit a service such as downforeveryoneorjustme.com and enter the website address. If the site is down globally, you will need to wait for the website owner to fix it.

Test on Another Device

Try accessing the website from a smartphone or tablet connected to the same Wi-Fi. If other devices also fail, the issue is likely with your router or internet connection rather than a single computer.

Temporarily Disable Security Software

Some firewall or antivirus applications can interfere with DNS requests. Temporarily disable your third-party security software and test the website. Remember to re-enable it immediately after testing.
