Have you ever come across ERR_CONNECTION_TIMED_OUT while trying to access a website on your Windows PC? This can happen in any browser when your Internet or server takes too long to respond. In this tutorial, we take a look at some solutions to help you solve this problem. They apply to Windows 11 and Windows 10 unless we have specified otherwise.


When you try to access a website and get the error message “ERR_CONNECTION_TIMED_OUT,” you might easily assume that your local network connection is having issues. However, that isn’t always the case.

When you want to visit a website, your computer sends a request to the server asking for access. Once the server validates your request, your browser connects to the website.

When you ask a website for access, a timer will start to run. If you don’t get the approval before the timer ends, you will see the ERR_CONNECTION_TIMED_OUT error in your browser.

Possible Causes of ERR_CONNECTION_TIMED_OUT Error

Some of the reasons that cause the ERR_CONNECTION_TIMED_OUT error include the following:

  • Server not found: one of the most common reasons for the connection timed out error is when you ask a server for access but the server is currently down, or you have entered an incorrect website address.
  • Server doesn’t respond: the server takes a long time to validate your connection request to give you access.
  • Slow internet connection: a slow and unreliable internet connection can take a few seconds or minutes to communicate with the server. In such a case, the browser will terminate your connection because it is taking too long to reach the server for access.
  • Server error: it is also possible that the server you’re trying to reach is slow and before it grants your access, the browser times out the connection.
  • Firewall: at times, your firewall could block access to certain websites because it suddenly stopped recognizing them or the website was blacklisted.


If you’ve come across this issue yourself, here are a few things that you need to try in order to get your browser up and running again. First off, check to see if your internet connection is working properly. After you’ve confirmed that, you can go ahead and try these fixes.

1. Turn Off Your Firewall

Your firewall may occasionally prevent you from accessing the Internet. So one thing to try when you can’t connect to the websites you want to visit is disabling your firewall.

  1. Click on the Search button in Windows and look for Windows Defender Firewall.
Opening Windows Defender Firewall by searching for it using the search button
  1. Click on “Turn Windows Defender Firewall on or off” from the left-side menu.
Opening the Windows Defender Firewall settings to turn it off
  1. Select “Turn off Windows Defender Firewall (not recommended)” under both “Private Network Settings” and “Public Network Settings.”
Turning off private network settings and public network settings
  1. Click “OK” to confirm.
  2. Restart your computer to apply the changes.

Tip: You can also completely disable Windows Defender if you want to.

If disabling the firewall didn’t fix the connection timeout problem, try the other solutions from this list.

2. Change the Timeout Duration

If your internet connection is slow, changing the timeout duration can help you connect to the web successfully. Follow these steps to do that:

  1. Click on the Search button, type “Registry Editor” and open it.
Opening Registry Editor by searching for it
  1. Go to the following path: “Computer\HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Internet Settings.”
Using the location path to create a registry file
  1. Right-click on the blank space inside the “Internet Settings” registry folder and click “New,” then select “DWORD (32-Bit) Value” and name it as “ReceiveTimeout.”
  1. To set your own timeout duration, multiply the seconds by 100. If you want to set the timeout duration to 5 minutes, enter the value 3000 after multiplying the seconds by 100 (300 X 100). If you want to change it to 10 minutes, you should enter the value 6000 (600 X 100).
Setting a timeout duration using a registry file
  1. Restart your PC.
  2. Now when your browser attempts to connect to a server for access, it will take longer before it times out.

3. Delete Your Browser’s History & Cache

Another thing you might want to try is deleting your browser history, caches, and cookies to remove all accumulated files. It could be this data that is preventing successful communication with the server or slowing down the communication.


  1. Open the Chrome browser.

4. Flush DNS Cache

DNS (Domain Name System) is like a phonebook for the Internet that keeps a database of all publicly accessible websites and their IP addresses. Sometimes, the DNS file on your PC can get corrupted, and your browser can fail to read the DNS to route you properly.

By clearing the DNS cache, you shall be resetting the DNS to its default state removing any corruption in the file that is causing the ERR_CONNECTION_TIMED_OUT error.

  1. Right-click on the Start button in Windows 11 and then select “Windows Terminal (Admin).” If you’re using Windows 10, select Run and type in the command wt, then press Enter.

In case your access is blocked or restricted, a VPN can bypass these limitations and connect to the website successfully.
