How To Fix “This Site Can’t Be Reached” Error

This Site Can’t Be Reached – Is it so annoying every time you see this error popping up? We bet that all of you would say yes, but “site cannot be reached” is a typical error that you might face while using the Internet. 

There are different error codes for “Chrome this site can’t be reached,” such as err_connection_refused, Server DNS address could not be found, and DNS_PROBE_FINISHED_NXDOMAIN.

Thus, it is hard to tell which method is specific to your problem. However, we will provide you with ten different methods to get rid of this error.

#1 Reset TCP/IP

When you first meet the “this site can’t be reached chrome” error, the simple method you could do is resetting TCP/IP. This method will fix the error if it comes from the current settings of your device.

Step 1: Run the “Command Prompt”

To find the Command Prompt, you could type “cmd” in the Start search box of your computer. Next is clicking on the “cmd” and choosing the “Run as administrator” option.

When you see the “User Account Control” window, select “Yes” to proceed to step 2.

Step 2: Run six commands

There are six commands that you must run in the Command Prompt:

  • ipconfig /release
  • ipconfig /all
  • ipconfig /flushdns
  • ipconfig /renew
  • netsh int IP set DNS
  • netsh Winsock reset

All you have to do is copying or typing exactly the above commands in the Command Prompt window, pressing Enter, and letting it run. Remember to run the command one by one.

Restart your device after the running commands process is over.  Now, check if you can access the site or not.  When you still see a “site cannot be reached”, it is time to try the second method.

#2 Change DNS Server Address

Do you know that your DNS server address may cause the “Gmail site can’t be reached” error? It is because we usually use IPv4 DNS Address automatically obtained or set up by Internet providers.

Step 1: To open the Run window, press the two buttons, “Windows key” and “R,” simultaneously.

Step 2: Type “ncpa.cpl” in the Run window and click “Ok.”

Step 3: Open the Internet Connection Status window by double-clicking the Internet Connection symbol. When you see the window, choose the Properties option on the screen.

Step 4: Find and double-click the “Internet Protocol Version 4 (TCP/IPv4)” line in the Networking tab.

Before clicking the Ok button, don’t forget to tick the “Validate settings upon the exit” option on the screen.

If all of the methods that work on your computer’s system are not helpful, you should try some ways to fix them on the Chrome settings. Allowing DNS Prefetching is one of the methods we recommend.

  • Step 1: On the right side of the Chrome window and near the Address bar, there is a three-dot button. Click on that button to open the menu for Chrome and select the Settings line.
  • Step 2: On the bottom of the Settings window, go to the Advanced Chrome Settings and access the Privacy section. Tick the “Use a prediction service to load pages more quickly” option.

If you can not find the Privacy section, your Chrome is out of date. As a result, updating on Chrome is necessary and this also could help fix the error without any other method.

#5 Use Windows Network Diagnostic

Now, you wait for Windows to finish the diagnosis process. After that, disconnecting and reconnecting your Internet is required before you access the site again to check.

#6 Disable Experimental QUIC Protocol

  • Step 1: Open your Chrome window and access “chrome://flags/” by type it in the address bar.
