The screen itself does not tell you the cause; the real clue is the <strong>error code<\/strong> written in small letters under the message (for example <code>ERR_CONNECTION_TIMED_OUT<\/code>).

If one of the first steps in this chain fails, the browser never receives the page and shows the &#8220;This site can&#8217;t be reached&#8221; screen. So the problem can be in DNS, in your network connection, in a firewall in between, or on the site&#8217;s server. The error code tells you which one.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Cause_and_Fix_by_Error_Code\"><\/span>Cause and Fix by Error Code<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<p class=\"wp-block-paragraph\">Find the code from the error screen in the table below and go to the related guide for the detailed fix:<\/p>\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Error code<\/th><th>What it means<\/th><th>Detailed guide<\/th><\/tr><\/thead><tbody><tr><td><code>ERR_CONNECTION_TIMED_OUT<\/code> \/ <code>ERR_TIMED_OUT<\/code><\/td><td>The server did not answer within a set time; the screen says the server took too long to respond.<\/td><td><a href=\"https:\/\/sunucun.com.tr\/blog\/fix-err-connection-timed-out\/\">ERR_CONNECTION_TIMED_OUT<\/a><\/td><\/tr><tr><td><code>ERR_CONNECTION_REFUSED<\/code><\/td><td>The server was reached, but the port refused the connection (service stopped or firewall).<\/td><td><a href=\"https:\/\/sunucun.com.tr\/blog\/fix-err-connection-refused\/\">ERR_CONNECTION_REFUSED<\/a><\/td><\/tr><tr><td><code>ERR_CONNECTION_RESET<\/code><\/td><td>After the connection was made, the other side or a device in between reset it.<\/td><td><a href=\"https:\/\/sunucun.com.tr\/blog\/err_connection_reset-en\/\">ERR_CONNECTION_RESET<\/a><\/td><\/tr><tr><td><code>ERR_CONNECTION_CLOSED<\/code> \/ <code>ERR_EMPTY_RESPONSE<\/code><\/td><td>The server closed the connection without sending a response.<\/td><td><a href=\"https:\/\/sunucun.com.tr\/blog\/fix-err-connection-closed\/\">ERR_CONNECTION_CLOSED<\/a><\/td><\/tr><tr><td><code>ERR_CONNECTION_ABORTED<\/code><\/td><td>The connection was cancelled midway, usually by security software or a network problem.<\/td><td><a href=\"https:\/\/sunucun.com.tr\/blog\/fix-err-connection-aborted\/\">ERR_CONNECTION_ABORTED<\/a><\/td><\/tr><tr><td><code>ERR_NAME_NOT_RESOLVED<\/code><\/td><td>The domain name could not be turned into an IP address (a DNS problem).<\/td><td><a href=\"https:\/\/sunucun.com.tr\/blog\/fix-err-name-not-resolved\/\">ERR_NAME_NOT_RESOLVED<\/a><\/td><\/tr><tr><td><code>DNS_PROBE_FINISHED_NXDOMAIN<\/code><\/td><td>DNS reported that no such domain exists.<\/td><td><a href=\"https:\/\/sunucun.com.tr\/blog\/dns_probe_finished_nxdomain-2\/\">DNS_PROBE_FINISHED_NXDOMAIN<\/a><\/td><\/tr><tr><td><code>ERR_ADDRESS_UNREACHABLE<\/code><\/td><td>No route to the target IP address could be found.<\/td><td><a href=\"https:\/\/sunucun.com.tr\/blog\/fix-err-address-unreachable\/\">ERR_ADDRESS_UNREACHABLE<\/a><\/td><\/tr><tr><td><code>ERR_NETWORK_CHANGED<\/code><\/td><td>Your network connection changed while the page was loading (Wi-Fi, VPN, IP change).<\/td><td><a href=\"https:\/\/sunucun.com.tr\/blog\/fix-err-network-changed\/\">ERR_NETWORK_CHANGED<\/a><\/td><\/tr><tr><td><code>ERR_QUIC_PROTOCOL_ERROR<\/code><\/td><td>A protocol error occurred on the QUIC\/HTTP3 connection.<\/td><td><a href=\"https:\/\/sunucun.com.tr\/blog\/fix-err-quic-protocol-error\/\">ERR_QUIC_PROTOCOL_ERROR<\/a><\/td><\/tr><tr><td><code>ERR_FAILED<\/code><\/td><td>The request failed for a general reason (cache, extension, CORS).<\/td><td><a href=\"https:\/\/sunucun.com.tr\/blog\/fix-err-failed\/\">ERR_FAILED<\/a><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n<p class=\"wp-block-paragraph\">Some errors come with a different screen instead of &#8220;This site can&#8217;t be reached&#8221; but belong to the same family: <a href=\"https:\/\/sunucun.com.tr\/blog\/fix-err-too-many-redirects\/\">ERR_TOO_MANY_REDIRECTS<\/a> and <a href=\"https:\/\/sunucun.com.tr\/blog\/fix-err-http2-protocol-error\/\">ERR_HTTP2_PROTOCOL_ERROR<\/a> on the &#8220;This page isn&#8217;t working&#8221; screen, the <a href=\"https:\/\/sunucun.com.tr\/blog\/what-is-a-503-error\/\">503 error<\/a> that shows the server temporarily cannot serve requests, and the <a href=\"https:\/\/sunucun.com.tr\/blog\/what-is-an-ssl-error\/\">SSL errors<\/a> seen with certificate problems (for example <a href=\"https:\/\/sunucun.com.tr\/blog\/fix-err-cert-authority-invalid\/\">NET::ERR_CERT_AUTHORITY_INVALID<\/a>).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Is_the_Problem_on_Your_Side_or_the_Sites\"><\/span>Is the Problem on Your Side or the Site&#8217;s?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<p class=\"wp-block-paragraph\">Separating the source of the problem before you start saves time:<\/p>\n\n\n<ul class=\"wp-block-list\"><li><strong>Do other sites open?<\/strong> If no site opens, the problem is your internet connection or your DNS setting.<\/li><li><strong>Does the site open from another network?<\/strong> Take your phone off Wi-Fi and try with mobile data.

Start with the simplest and go in order:<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"1_Check_the_Address_and_Reload_the_Page\"><\/span>1. Check the Address and Reload the Page<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">Make sure there is no typo in the domain name and reload the page. With short network interruptions, a second try is often enough.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_Restart_the_Router_and_the_Computer\"><\/span>2. Restart the Router and the Computer<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">Turn off the router, wait 30 seconds and turn it back on. This clears the router&#8217;s connection table and DNS cache.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"3_Try_an_Incognito_Window_and_Turn_Off_Extensions\"><\/span>3. Try an Incognito Window and Turn Off Extensions<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">If the site opens in an incognito window, the problem is the browser cache or an extension. Clear the cache and turn extensions off one by one to find the one causing it.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"4_Reset_the_DNS_Cache_and_Network_Settings\"><\/span>4. Reset the DNS Cache and Network Settings<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">On Windows, open Command Prompt as administrator, run these commands, and then restart the computer:<\/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\">To clear Chrome&#8217;s own DNS cache, type <code>chrome:\/\/net-internals\/#dns<\/code> in the address bar and press the &#8220;Clear host cache&#8221; button.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"5_Use_a_Different_DNS_Server\"><\/span>5. Use a Different 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, addresses cannot be resolved. In the network adapter settings, set a public DNS server such as Cloudflare (<code>1.1.1.1<\/code>) or Google (<code>8.8.8.8<\/code>) and try again.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"6_Check_VPN_Proxy_and_Security_Software\"><\/span>6. Check VPN, Proxy and Security Software<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">If a VPN or proxy is on, turn it off and try again; if it is off and the site fails only on your network, there may be an access block. The web protection in antivirus software and firewalls can block some sites; turn it off briefly to test, then turn it back on.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"7_%E2%80%9CThis_Site_Cant_Be_Reached%E2%80%9D_on_a_Phone\"><\/span>7. &#8220;This Site Can&#8217;t Be Reached&#8221; on a Phone<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">On Android and iPhone, switch between Wi-Fi and mobile data, turn airplane mode on and off, and clear the browser cache. On Android, if the &#8220;Private DNS&#8221; setting is on and points to a wrong server, addresses cannot be resolved; try the setting on &#8220;Automatic&#8221; or with a valid provider.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_to_Check_as_a_Site_Owner\"><\/span>What to Check as a Site Owner<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<p class=\"wp-block-paragraph\">If your site does not open from any network, look for the problem on the server and domain side:<\/p>\n\n\n<ol class=\"wp-block-list\"><li><strong>Domain and DNS records:<\/strong> Make sure the domain has not expired and that the A\/AAAA records point to the right IP address. You can check with <code>nslookup yourdomain.com<\/code> or <code>dig yourdomain.com<\/code>.<\/li><li><strong>Server and web service:<\/strong> Check that the server is up and the web service (Nginx, Apache, LiteSpeed) is running.<\/li><li><strong>Ports and firewall:<\/strong> Confirm that ports 80 and 443 are open to the outside. On Linux you can see listening ports with <code>ss -tlnp<\/code>.<\/li><li><strong>Resource usage:<\/strong> When CPU, memory or disk is full, the server cannot answer connections and time-out errors start.<\/li><li><strong>Error logs:<\/strong> The web server&#8217;s error logs often show the cause directly.<\/li><\/ol>\n\n\n<p class=\"wp-block-paragraph\">If you want full access to the server, your own firewall rules and the ability to read the logs, you can use a <a href=\"https:\/\/sunucun.com.tr\/en\/vds-server\">VDS server<\/a> with root access.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<p class=\"wp-block-paragraph\">&#8220;This site can&#8217;t be reached&#8221; is not a single error but a general screen showing that the connection could not be made.
