Chrome then displays the &#8220;This site can&#8217;t be reached&#8221; page with the message &#8220;\u2026 took too long to respond&#8221; below it. In this guide we explain what the error means, why it happens and how to fix it step by step, both as a visitor and as a site owner.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Does_ERR_CONNECTION_TIMED_OUT_Mean\"><\/span>What Does ERR_CONNECTION_TIMED_OUT Mean?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<p class=\"wp-block-paragraph\">When you open a site, the browser first translates the domain name into an IP address and then sends a connection request to the server at that IP address (usually on port 443 or 80). If the server does not answer this request within a reasonable time, the browser stops waiting and shows <code>ERR_CONNECTION_TIMED_OUT<\/code>. In other words, the request was lost somewhere or silently blocked; the server did not even say &#8220;no&#8221;.<\/p>\n\n\n<p class=\"wp-block-paragraph\">This error is different from other connection errors that look similar:<\/p>\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Error<\/th><th>What is happening?<\/th><\/tr><\/thead><tbody><tr><td>ERR_CONNECTION_TIMED_OUT<\/td><td>No response came from the server and the wait time ran out<\/td><\/tr><tr><td>ERR_CONNECTION_REFUSED<\/td><td>The server was reached but refused the connection (closed port or service not running)<\/td><\/tr><tr><td>ERR_CONNECTION_RESET<\/td><td>The connection was established but cut off midway<\/td><\/tr><tr><td>ERR_NAME_NOT_RESOLVED<\/td><td>The domain name could not be translated into an IP address (DNS problem)<\/td><\/tr><tr><td>504 Gateway Timeout<\/td><td>The server was reached but the application behind it did not respond in time<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n<p class=\"wp-block-paragraph\">For the case where the connection is cut off midway, see our article on the <a href=\"https:\/\/sunucun.com.tr\/blog\/err_connection_reset-en\/\">ERR_CONNECTION_RESET error<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Is_It_Different_from_ERR_TIMED_OUT\"><\/span>How Is It Different from ERR_TIMED_OUT?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\"><strong>ERR_TIMED_OUT<\/strong> is also a timeout error, but it can also appear when the connection has been established and the server then takes too long to send its response. Chrome shows one of the two codes depending on the stage at which it was waiting; the causes and fixes are largely the same, so the steps below apply to both errors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Causes_of_the_ERR_CONNECTION_TIMED_OUT_Error\"><\/span>Causes of the ERR_CONNECTION_TIMED_OUT Error<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<ul class=\"wp-block-list\"><li><strong>Internet connection or router problem:<\/strong> If the connection is down or very slow, requests do not arrive in time.<\/li><li><strong>Firewall or antivirus block:<\/strong> Security software on the computer or the network can drop the request without answering.<\/li><li><strong>Wrong proxy or VPN setting:<\/strong> A browser trying to go out through a proxy server that does not work gets no response.<\/li><li><strong>Old or wrong DNS record:<\/strong> If the domain resolves to an old IP address, the browser waits for a server that is no longer there.

If the site opens on mobile data, the problem is most likely on your network or device; apply the steps below in order.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"1_Check_Your_Internet_Connection_and_Router\"><\/span>1. Check Your Internet Connection and Router<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">See whether other sites open. If they do not, turn the router off, wait 30 seconds and turn it back on.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_Clear_the_Browser_Cache_and_Cookies\"><\/span>2. Clear the Browser Cache and Cookies<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">In Chrome, clear browsing data with <strong>Ctrl + Shift + Delete<\/strong> and try opening the site in an incognito window. If it opens in incognito, an extension may be causing the problem; try turning extensions off one by one.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"3_Flush_the_DNS_Cache_and_Renew_Your_IP_Address\"><\/span>3. Flush the DNS Cache and Renew Your IP Address<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">On Windows, open Command Prompt as administrator and run these commands in order:<\/p>\n\n\n<pre class=\"wp-block-code\"><code>ipconfig \/flushdns\nipconfig \/release\nipconfig \/renew\nnetsh winsock reset<\/code><\/pre>\n\n\n<p class=\"wp-block-paragraph\">Restart the computer after the last command.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"4_Change_Your_DNS_Server\"><\/span>4. Change Your DNS Server<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">If your internet provider&#8217;s DNS server is slow or faulty, try switching to a public DNS such as Google (8.8.8.8) or Cloudflare (1.1.1.1). If DNS is the problem, our article on <a href=\"https:\/\/sunucun.com.tr\/blog\/dns-server-not-responding-mean\/\">DNS server not responding<\/a> may also help.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"5_Check_Proxy_and_VPN_Settings\"><\/span>5. Check Proxy and VPN Settings<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">On Windows, if a manual proxy is set under <strong>Settings &gt; Network &amp; Internet &gt; Proxy<\/strong>, turn it off. If you use a VPN, turn it off and try again.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"6_Temporarily_Turn_Off_the_Firewall_and_Antivirus\"><\/span>6. Temporarily Turn Off the Firewall and Antivirus<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">Turn your security software off for a short time and try opening the site. If the site opens, allow it in the software&#8217;s settings and turn protection back on.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"7_Check_the_hosts_File\"><\/span>7. Check the hosts File<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">On Windows, if the <code>C:WindowsSystem32driversetchosts<\/code> file contains an old IP address for the site&#8217;s domain, the browser goes to the wrong server.
