In this post, you\u2019ll learn 10 methods to fix this problem on Windows, Mac, and other devices. Each method includes step-by-step instructions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Does \u201cDNS Address Could Not Be Found\u201d Mean?<\/h2>\n\n\n\n<p>Before fixing the issue, it helps to understand what\u2019s happening behind the scenes. <a href=\"https:\/\/lightningxvpn.com\/blog\/en\/what-is-dns\/\" target=\"_blank\" rel=\"noopener\" title=\"\">DNS<\/a> (Domain Name System) acts like the Internet\u2019s phonebook. When you type a website address, your device asks a DNS server to find the correct IP.<\/p>\n\n\n\n<p>If that process fails, your browser shows errors like \u201cDNS address could not be found\u201d or \u201cserver DNS address could not be found\u201d, even if your internet connection appears active.<\/p>\n\n\n\n<p><strong>Common causes of this error:<\/strong><\/p>\n\n\n\n<ul>\n<li>Your device isn\u2019t properly connected to the network.<\/li>\n\n\n\n<li><a href=\"https:\/\/lightningxvpn.com\/blog\/en\/fix-dns-server-not-responding\/\" target=\"_blank\" rel=\"noopener\" title=\"\">DNS server not responding<\/a>: The DNS server from your ISP is down or overloaded.<\/li>\n\n\n\n<li>Wrong or misconfigured DNS settings on your device.<\/li>\n\n\n\n<li>Corrupted DNS cache.<\/li>\n\n\n\n<li>Router or modem problems.<\/li>\n\n\n\n<li>VPNs or proxies are blocking or misrouting DNS requests.<\/li>\n\n\n\n<li>Firewall or antivirus blocking DNS.<\/li>\n\n\n\n<li>Outdated network drivers.<\/li>\n\n\n\n<li>The website\u2019s own DNS records are missing or misconfigured.<\/li>\n\n\n\n<li>Your internet service provider is experiencing DNS problems.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Fix 1: Check Your Internet Connection<\/h2>\n\n\n\n<p>Sometimes the error has nothing to do with DNS itself. A weak or disconnected network can trigger the \u201cDNS address could not be found\u201d message.<\/p>\n\n\n\n<p><strong>Steps:<\/strong><\/p>\n\n\n\n<ol start=\"1\">\n<li>Make sure Wi-Fi or Ethernet is well-connected.<\/li>\n\n\n\n<li>Restart your modem and router.<\/li>\n\n\n\n<li>Try opening a different website.<\/li>\n\n\n\n<li>Test your internet connection on another device.<\/li>\n<\/ol>\n\n\n\n<p>If multiple devices fail, the issue may be network-related rather than DNS-specific.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Fix 2: Restart Your Device<\/h2>\n\n\n\n<p>Temporary system glitches can cause a \u201cServer DNS address could not be found\u201d error.
