DNS_PROBE_FINISHED_NXDOMAIN might look like the title of an alien field report, but it\u2019s just an error code from your browser, and it means one specific thing: the Domain Name System (DNS) couldn\u2019t find the website you asked for.<\/p>\n\n\n\n

Here\u2019s the good news: the website itself is usually fine. Most of the time the problem lives on your own device (a stale DNS cache, a misconfigured network setting, or a plain old typo), and you can fix it in a few minutes.<\/p>\n\n\n\n

In this guide, we\u2019ll explain what the error actually means and what causes it, then walk through the fixes step by step: first for visitors on Windows, Mac, Android, and iPhone, and then for site owners whose visitors keep hitting the error.<\/p>\n\n\n\n

What Does DNS_PROBE_FINISHED_NXDOMAIN Mean?<\/h2>\n\n\n\n

DNS_PROBE_FINISHED_NXDOMAIN is a browser error meaning the Domain Name System (DNS) couldn\u2019t find an IP address for the domain you typed. NXDOMAIN stands for \u201cnon-existent domain\u201d: every DNS server that was asked reported that the name doesn\u2019t exist, so your browser has nowhere to send the request.<\/p>\n\n\n\n\n\n

What is DNS?<\/h3>\n

The Domain Name System (DNS) protocol keeps records of which domain names correspond to specific IP addresses. This system enables you to browse the web by typing in regular URLs instead of IP addresses.<\/p>\n \n Read More <\/a>\n\n<\/div>\n\n\n\n

\"The<\/figure>\n\n\n\n

Think of DNS as the web\u2019s phone directory: it\u2019s the reason you can type \u201cdreamhost.com\u201d instead of memorizing a string of digits for every website you visit.<\/p>\n\n\n\n

When you type a web address, your device asks a DNS resolver (usually run by your internet service provider, or a public provider like Google or Cloudflare) to look up the domain\u2019s IP address. If the resolver doesn\u2019t already have the answer cached, it works down the DNS hierarchy: the root servers point it to the servers for the top-level domain (like .com), and those point it to the domain\u2019s authoritative nameservers, which hold the actual records. The whole chain usually takes a fraction of a second.<\/p>\n\n\n\n

If the authoritative servers say the name doesn\u2019t exist, or the domain has been removed from the registry\u2019s zone entirely, the resolver returns the NXDOMAIN answer. It\u2019s an official DNS response: the \u201cName Error\u201d code dates back to the original DNS specification (RFC 1035), and the IETF\u2019s RFC 2308<\/a> gave it the NXDOMAIN name, describing it as meaning the queried domain \u201cdoes not exist.\u201d<\/p>\n\n\n\n

And the \u201cPROBE_FINISHED\u201d part? When a page fails to load because of a DNS problem, Chrome runs a quick diagnostic probe to pin down the exact cause. This error name is the probe\u2019s verdict: the check finished, and the answer was NXDOMAIN.<\/p>\n\n\n\n

The error code itself is specific to Chromium-based browsers \u2014 Google Chrome, Microsoft Edge, Brave, and Opera \u2014 though each browser dresses it differently. The same DNS failure looks like this across browsers:<\/p>\n\n\n\n
