Chrome then shows the message &#8220;\u2026 server IP address could not be found&#8221; on the &#8220;This site can&#8217;t be reached&#8221; page, together with the code <code>ERR_NAME_NOT_RESOLVED<\/code>. In this guide we explain what the error means, what causes it and how to fix it on a computer, on a phone and as a site owner.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Does_ERR_NAME_NOT_RESOLVED_Mean\"><\/span>What Does ERR_NAME_NOT_RESOLVED Mean?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<p class=\"wp-block-paragraph\">Every site on the internet runs at an IP address; domain names exist to make these addresses easy to remember. When you open a site, your device first asks a <strong>DNS server<\/strong>, &#8220;what is the IP address of this domain?&#8221; If the DNS server cannot answer, answers wrongly, or the domain&#8217;s record cannot be found, the browser does not know which server to connect to and the ERR_NAME_NOT_RESOLVED error appears. In short, the problem is not the site itself but the step where the name is translated into an address.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Causes_of_the_ERR_NAME_NOT_RESOLVED_Error\"><\/span>Causes of the ERR_NAME_NOT_RESOLVED Error<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<ul class=\"wp-block-list\"><li><strong>The address is mistyped:<\/strong> A single wrong letter in the domain makes the device look up a name that does not exist.<\/li><li><strong>The DNS server is not responding:<\/strong> The DNS service of your internet provider or router may be temporarily down.<\/li><li><strong>Stale DNS cache:<\/strong> Your device or browser may remember an old record for the domain that is no longer valid.<\/li><li><strong>The domain has expired or has no DNS record:<\/strong> If the domain was not renewed or its A record was deleted, no DNS server can return an IP address.<\/li><li><strong>A nameserver change has not propagated yet:<\/strong> If the domain&#8217;s DNS servers were changed recently, the record may not be found on some networks for a while.<\/li><li><strong>Security software, VPN or a custom DNS setting:<\/strong> An app that filters DNS queries, or a mistyped custom DNS address, can block the lookup.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Fix_ERR_NAME_NOT_RESOLVED_on_a_Computer\"><\/span>How to Fix ERR_NAME_NOT_RESOLVED on a Computer<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"1_Check_the_Address_and_Your_Internet_Connection\"><\/span>1. Check the Address and Your Internet Connection<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">Make sure the domain in the address bar is spelled correctly and see whether other sites open. If no site opens, restart your router.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_Flush_the_DNS_Cache\"><\/span>2.

To clear Chrome&#8217;s own DNS cache, type <code>chrome:\/\/net-internals\/#dns<\/code> in the address bar and click <strong>Clear host cache<\/strong>.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"3_Change_Your_DNS_Server\"><\/span>3. Change Your DNS Server<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">The most common lasting fix is to use a reliable public DNS instead of your internet provider&#8217;s DNS. On Windows, go to <strong>Control Panel &gt; Network and Sharing Center &gt; Change adapter settings<\/strong> and enter these addresses in the <strong>Internet Protocol Version 4 (TCP\/IPv4)<\/strong> properties of your connection:<\/p>\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Provider<\/th><th>Preferred DNS<\/th><th>Alternate DNS<\/th><\/tr><\/thead><tbody><tr><td>Google<\/td><td>8.8.8.8<\/td><td>8.8.4.4<\/td><\/tr><tr><td>Cloudflare<\/td><td>1.1.1.1<\/td><td>1.0.0.1<\/td><\/tr><tr><td>Quad9<\/td><td>9.9.9.9<\/td><td>149.112.112.112<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"4_Check_Secure_DNS_in_Chrome\"><\/span>4.

You can also turn extensions off or use an incognito window to see whether an extension is interfering with lookups.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"5_Check_VPN_Proxy_and_Security_Software\"><\/span>5. Check VPN, Proxy and Security Software<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">If you use a VPN or proxy, turn it off and try again. The web protection feature of an antivirus or firewall may be blocking DNS queries; turn it off temporarily to test. Also check that the <code>hosts<\/code> file has no faulty line for the domain.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"ERR_NAME_NOT_RESOLVED_on_Android_and_iPhone\"><\/span>ERR_NAME_NOT_RESOLVED on Android and iPhone<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<ul class=\"wp-block-list\"><li><strong>Android:<\/strong> Clear Chrome&#8217;s cache under <strong>Settings &gt; Apps &gt; Chrome &gt; Storage &gt; Clear cache<\/strong>.

With ERR_NAME_NOT_RESOLVED the internet usually works but a particular domain cannot be resolved; with DNS_PROBE_FINISHED_NO_INTERNET the device cannot reach the internet at all. To fix it, first check the Wi-Fi or cable connection, the router and the network adapter; on Windows, the network troubleshooter and the <code>netsh winsock reset<\/code> command bring the connection back in most cases. For the case where the domain cannot be found at all, see our article on the <a href=\"https:\/\/sunucun.com.tr\/blog\/dns_probe_finished_nxdomain-2\/\">DNS_PROBE_FINISHED_NXDOMAIN error<\/a>, and for the case where the DNS server does not answer at all, see <a href=\"https:\/\/sunucun.com.tr\/blog\/dns-server-not-responding-mean\/\">DNS server not responding<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"For_Site_Owners_If_Your_Site_Returns_ERR_NAME_NOT_RESOLVED\"><\/span>For Site Owners: If Your Site Returns ERR_NAME_NOT_RESOLVED<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<p class=\"wp-block-paragraph\">If your site shows this error on other networks and devices too, the problem is in your domain&#8217;s DNS configuration:<\/p>\n\n\n<ol class=\"wp-block-list\"><li><strong>Check the domain&#8217;s expiry:<\/strong> DNS is suspended for expired domains.
