DNS Probe Finished NXDOMAIN

What is DNS_PROBE_FINISHED_NXDOMAIN?

A common browser error code displaying when the web browser cannot resolve a website's domain name because the DNS server reports that the domain name does not exist (Non-Existent Domain).

Common Causes

• Corrupt local DNS resolver cache
• Incorrect network DNS servers
• VPN/firewall blocking DNS requests

Step-by-Step Fix Guide

• 1
  Flush DNS resolver cache

  Flushing the DNS cache removes bad hostname-to-IP records stored locally.

• 2
  Change DNS servers to Google DNS (8.8.8.8) or Cloudflare DNS (1.1.1.1)

  Changing to reliable public servers bypasses failures in your ISP's custom DNS nameservers.

• 3
  Restart the router
