ERR_CONNECTION_TIMED_OUT

How To Fix "ERR_CONNECTION_TIMED_OUT" Google Chrome Error?

Google Chrome is one of the most popular web browsers, but despite its popularity, it is not without problems. You may have experienced the "ERR_CONNECTION_TIMED_OUT" error. This is not a problem with the browser, but usually means that there are problems at the user end, such as internet connection issues. This error, or similar, can occur not only with Google Chrome, but also, with other browsers. Furthermore, it can occur on any website, even the most popular.

The error can occur due to problems with the DNS (Domain Name System) server, which does not respond or any has other issues. As the error message states, to fix the problem, you should check your connection, check proxy and firewall settings, or run Windows Network Diagnostics. One of these methods might solve the problem, however, there are others, such as flushing the DNS, changing the DNS server, checking Windows Hosts file, updating network adapter drivers, and so on.

Fortunately, it is possible to fix this error if there are problems with the operating system, rather than the ISP (Internet Service Provider). In other words, if the cause of the error is at the user end, there are various methods to solve the problem. In the guide below, we outline these methods in detail so that you will be able to connect to the internet and visit web pages again.

Flush DNS And Renew IP

Start with this method, which works for most users who encounter the "ERR_CONNECTION_TIMED_OUT" error. The method includes entering and executing "ipcofig" and "netsh" commands into Command Prompt. Ipconfig is a command-line tool that displays the current configuration of the installed IP stack on a networked computer. Using this tool, we can flush and reset the contents of the DNS client resolver cache and renew DHCP configuration. Netsh is a command-line scripting utility that allows you to (either locally or remotely) display or modify the network configuration of a computer that is currently running. Netsh also provides a scripting feature that allows you to run a group of commands in batch mode against a specified computer.

The commands require an elevated Command Prompt opened with administrator privileges. To open elevated Command Prompt, type "command prompt" in Search and right-click on the "Command Prompt" result. Choose "Run as administrator" to run it with administrative privileges. When you select "Run as administrator", a User Account Control prompt will appear asking if you allow the Command Prompt to make changes to your computer. Click "Yes".

Use Google DNS

Google's Public DNS is a free alternative Domain Name System (DNS) service offered to internet users around the world. The public DNS service and servers are maintained and owned by Google. It functions as a recursive name server providing domain name resolution for any host on the internet. We recommend that you use Google DNS for a faster and secure connection. You must change the DNS manually as described below.

To change your DNS server to Google's DNS server, go to Network Connections settings. Right-click the Start menu and select "Network Connections", or go to Settings and click "Network & Internet".

Click "OK" to save changes. Restart your computer and see if the "ERR_CONNECTION_TIMED_OUT" error is fixed.

Clear Browsing Data

Browsing data consists of a records of web pages that you have visited in past browsing sessions, and typically includes the name of the website as well as its corresponding URL. Other private data components such as cache, cookies, saved passwords, etc., are also saved during your browsing session. This stored data can slow down your browser and browsing experience, and even cause problems such as the "ERR_CONNECTION_TIMED_OUT" error. To clear Google Chrome's browsing data cache, click the three dots in the top-right corner, select "More tools" and click "Clear browsing data...".

clear browsing data step 1

In the Clear browsing data window, select the data you want to remove from the Google Chrome browsing cache and click the "CLEAR DATA" button. Close Chrome and open it again - see if the "ERR_CONNECTION_TIMED_OUT" still occurs when you try to visit web pages.

Temporarily Disable Your Antivirus

It is possible that your antivirus (anti-malware) software is blocking access to some or all websites. To ensure that installed third-party antivirus software is not causing this error, we recommend that you temporarily disable it and check if the error persists. If disabling (or uninstalling) your antivirus helps, we recommend that you switch to another antivirus software (or try reinstalling the currently one). If you are not sure how to disable antivirus software, read this guide where you will find instructions on how to disable some of the most popular antivirus programs.

Update Network Adapter's Driver

A device driver is software that informs the operating system and other software how to interact with specific hardware. It is rather like a translator between software and hardware, since they often are created by different manufacturers, companies, or people. The driver facilitates smooth communication between hardware and software. In most cases, computers are unable to send and receive data correctly without drivers. If the appropriate driver is not installed, the device might not function properly. To reinstall the network adapter driver, use Device Manager. To open Device Manager, right-click the Start button and select the "Device Manager" result from the contextual menu or type "device manager" in Search and click the "Device Manager" result.

update network adapter driver step 1

In Device Manager, you will see a list of devices connected to your computer. Find "Network adapters", expand it and right-click your networking device. Select the "Update driver" option from the contextual menu.

update network adapter driver step 2

You will be asked if you want to search for updated driver software automatically or to browse your computer for driver software. If you select the first option, Windows will search your computer and the Internet for the latest driver software for your device. If you select the second option, you must locate and install the drivers manually. Using this option requires having previously downloaded drivers on your computer or USB flash drive. We recommend that you select the first option and follow the instructions.

update network adapter driver step 3

The first option does not solve the problem, download the latest network adapter driver from the manufacturer's websites, or reinstall the driver. To reinstall it, choose the "Uninstall device" option when right-clicked on network adapter. Mark the "Delete the driver software for this device" checkbox if you see this option. Then Restart your computer and see if it fixed the "ERR_CONNECTION_TIMED_OUT" error.

If you have tried all of the above and "ERR_CONNECTION_TIMED_OUT" persists, you might want to contact your Internet Service Provider (ISP) and find out if the problem is at their end. You can also simply switch to another browser and check if you are able to visit websites. If you know of other solutions to this problem, not mentioned in our guide, please share them with us by leaving a comment in the section below.
