In this case the phone looks connected to Wi-Fi or mobile data, but sites won&#8217;t open or apps show a &#8220;No internet connection&#8221; error.<\/p>\n<p>In this article we explain step by step why the error happens and how to fix it in a few minutes.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Is_Private_DNS_and_Why_Does_It_Fail\"><\/span>What Is Private DNS and Why Does It Fail?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Private DNS is a feature in Android 9 and later. It encrypts your DNS queries with <strong>DNS-over-TLS<\/strong> and sends them to the DNS provider you choose, so the network you&#8217;re on can&#8217;t see which sites you look up. This connection usually uses <strong>port 853<\/strong>.<\/p>\n<p>When the phone can&#8217;t reach this server, it can&#8217;t translate domain names into IP addresses and the internet appears not to work. The most common causes:<\/p>\n<ul>\n<li>The provider hostname is misspelled, or an IP address was entered instead of a hostname<\/li>\n<li>The Wi-Fi network (school, workplace, hotel, caf\u00e9) blocks port 853<\/li>\n<li>You&#8217;re on a network with a login page (captive portal) and haven&#8217;t signed in<\/li>\n<li>A temporary outage at the chosen DNS provider<\/li>\n<li>A conflict with VPN or ad-blocker apps<\/li>\n<li>The phone&#8217;s date and time are wrong (the encrypted connection requires certificate validation)<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Quick_Fix_Set_Private_DNS_to_Automatic\"><\/span>Quick Fix: Set Private DNS to Automatic<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If you need internet access right away, the fastest fix is to set Private DNS to <strong>Automatic<\/strong> or <strong>Off<\/strong>:<\/p>\n<ol>\n<li>Go to <em>Settings \u2192 Network &amp; internet \u2192 Private DNS<\/em>.<\/li>\n<li>Select <strong>Automatic<\/strong> and tap <strong>Save<\/strong>.<\/li>\n<\/ol>\n<p>On Samsung phones the path is <em>Settings \u2192 Connections \u2192 More connection settings \u2192 Private DNS<\/em>. Menu names may differ on Xiaomi and other brands; you can find it by typing &#8220;DNS&#8221; in the settings search bar.<\/p>\n<p>In <em>Automatic<\/em> mode, the phone uses encrypted DNS if the network supports it and falls back to normal DNS if it doesn&#8217;t, so no error appears.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"If_You_Want_to_Keep_Using_Private_DNS\"><\/span>If You Want to Keep Using Private DNS<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"1_Check_the_hostname\"><\/span>1. Check the hostname<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The Private DNS field takes a <strong>hostname, not an IP address<\/strong>.

Compare Wi-Fi and mobile data<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>If the error only appears on a particular Wi-Fi network, that network most likely blocks port 853 or is waiting for a login page. On such networks, set Private DNS to <em>Automatic<\/em>; if the network has a login page, sign in first.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"4_Turn_off_VPN_and_ad_blockers\"><\/span>4.
