11 Best Ways to Fix “ERR_CONNECTION_CLOSED” in Chrome

What is the Meaning of the ERR_CONNECTION_CLOSED Error?

When you try to access a website but encounter an error message “ERR_CONNECTION_CLOSED”. This means your computer or PC is unable to connect to the website you were trying to access. It is a simple way for Chrome to tell its users that data transferred to establish a connection has been interrupted due to unavoidable circumstances.

Let us get into more details and see exactly what happens when you try to access a website at the backend of Chrome.

The moment you enter your website URL in your browser’s address bar and hit “Enter” or click on a link, the Chrome browser will try to make a connection to that server.

When the Chrome browser is successfully able to establish a connection with the server, it will start requesting the necessary files such as images, codes, etc. that are required to render the webpage.

But due to any unavoidable circumstances, if something went wrong with your PC or computer or the internet connection went off, the Chrome browser will not be able to establish or continue the connection with the server.

So, due to this, the chrome browser will also be unable to render the webpage/website and as a result, it will display an error message “ERR_CONNECTION_CLOSED” on your display.

In order to solve the ERR_CONNECTION_CLOSED error, the first thing you need to figure out is its possible causes and why your Chrome is unable to establish a connection with the server.

What are the Possible Reasons that can Cause the ERR_CONNECTION_CLOSED error?

There can be multiple reasons for causing errors, but these are the most common reasons that trigger the ERR_CONNECTION_CLOSED error when you browse a website.

• Poor internet connectivity
• Misconfigured network settings
• Firewalls or Antivirus blocking
• ISP has blocked that website
• The problem from the DNS side
• Browser Cache memory
• Malfunctioning of Chrome extension
• Outdated Chrome Browser

Now, let us see what various methods you can try to fix the ERR_CONNECTION_CLOSED error easily.

How to Fix the ERR_CONNECTION_CLOSED Error in Chrome?

Here we are providing your 11 best ways to fix the Err_connection_closed error as well and you will be able to determine the culprit that triggers it.

1. Examine Your Internet Connectivity

When the ERR_CONNECTION_CLOSED error message displays on your screen, the first and foremost step you need to do is to check if your internet connection is working or not. If there are any sudden drops in internet connectivity or the connection is unstable, your Chrome browser will start showing you this error.

The sudden drop in internet connection can happen due to various reasons such as the cable having been plugged out, loose connection ports, a Faulty router, poor router signal strength, and many more.

The easiest way to figure out this is to try accessing the internet via an alternate device such as your smartphone, any desktop, or laptop and see if you are able to access the internet or not.

If not, check if your router is working, the power supply to it, or even configure its settings. In addition to that, make sure your internet wire is not broken and the ports are not loose.

2. Reset Your Internet Connectivity Settings

Even though your internet connection and the hardware part are working fine. The error can still be triggered due to misconfiguration of internet/network settings in your device.

Generally, this issue can be fixed or resolved by simply resetting your TCP/IP to its initial state.

Resetting Network Settings in Windows

For Windows users, you have to open the command prompt under the “Run as an administrator” option. After that, you have to enter some commands as given below:

First, these commands will help to reset your TCP/IP settings.

netsh int ip reset

After that, you have to reset your Winsock (Windows Sockets Interface) by running the commands as follows:

netsh winsock reset

To complete the process, restart your system/PC and check if the error has been fixed or not.

Resetting Network Settings in macOS

If you are a macOS user, you are not required to use any command line to reset the network. All you need to do is to

• Go to System Preferences and Open it.
• Then click on Network Settings to open.
• Choose the internet connection that is marked as connected.
• Now click on the advanced option that is located at the bottom right corner.
• Navigate to the TCP/IP tab via Advanced settings
• Click on the button to reset or renew the DHCP lease.

3. Deactivate Any Proxy Server or VPN in Use

If you are using a proxy server or a VPN, if misconfigured it can also trigger an ERR_CONNECTION_CLOSED error. Since a Proxy server or VPN helps you to get anonymous while surfing the internet on the web, both these solutions are highly involved in the data process as well. Which increases the risk of complications and as a result sometimes causes an ERR_CONNECTION_CLOSED error.

Therefore, by any chance, if you are using any of these two arrangements, you must deactivate it and see if the error persists. If your Chrome browser starts properly now you know what is causing the issue.

If you are using VPN software, you have to disable it through its settings. But if you are using a Chrome extension, in this case, all you need to simply disable it from Chrome > Settings > Extensions.

Deactivate the Proxy Server in Windows

To deactivate or disable any proxy server in Windows, you have to follow the steps given below:

• Go to your Windows control panel and search “Internet options“.
• Click on the “Internet options” and a pop-up window will appear with all the Internet properties.
• Now click on the connections tab > LAN settings
• Uncheck the “Automatically detect Settings” and mark the box ” Use a proxy server for your LAN“.

Deactivate the Proxy Server in macOS

For Mac users, their complete documentation is provided by Apple on their support page, to change Proxy Settings. You can check out that dedicated Apple support page here.

3. Clear Your Chrome Browser History and Cache

To enhance the user experience and seep up the browsing experience, your Chrome browser tends to save some of the website files as cache memory. If anything goes wrong and your stored cache memory gets corrupted, then it will start triggering WordPress errors like ERR_CONNECTION_CLOSED.

Therefore, the best solution to fix this issue is to clear or purge the complete browsing history. To do so, follow this path:

Go to your Chrome browser > Settings > Privacy and Security > Clear browsing data > You can uncheck the Browsing History and let cookies and other site data, as well as cache images, checked > Clear data.

Or

Enter the following address directly to your Chrome browser address bar: chrome://settings/privacy and click on Clear browsing data.

In the pop-up window, you will see plenty of other options, but you have to choose as follows:

• Select the time range as “All time”.
• Select cookies and other site data as well as Cache images (you can also select browsing history)
• Click on the Clear Data button.

4. Clear Your DNS Cache

In addition to clearing your browser cache memory, you should also clear or flush your DNS cache.

When you visit a website, your device or browser first looks up the original IP address of the server which is connected to the domain name of the website you visit. This process generally takes time and hence increases the page loading speed.

Therefore, to minimize this time, your browser stores the IP addresses of servers in a DNS cache locally. But, for some reason, if this DNS cache got corrupted to store incorrect data, it will start triggering the ERR_CONNECTION_CLOSED error message on your screen.

Therefore, to fix this issue, the best solution is to flush the DNS cache of your PC or computer. We have posted a dedicated article on “How to Easily Flush DNS Command Cache (Windows, Mac, Linux)“, from where you can easily flush your DNS cache in any device available.

After flushing the DNS cache from your System, device, or PC, the next thing you need to do is to flush DNS from your Chrome browser.

To do so, the shortcut method is to enter the following address in your Chrome browser address bar:

chrome://net-internals/#dns

And click on “Clear host cache“.

5. Change DNS Settings

The ISP usually supplies DNS Server addresses, and the users can change this temporarily while facing issues. There are two popular public domains today, which are known to be secure and have a large user database. One is Google’s Public DNS, and the other one is Cloudflare.

Some use-free DNS servers, where the case of err_connection_closed is imminent. During this instance, simply switching to Google and Cloudflare servers easily resolves the issues as well. For changing the same, here are steps for different O/S as follows,

For Windows

Opening Up the Control Panel, by typing the same in the run command box

Clicking on the Network and Internet option will open up loads of other options.

Next, click on the “Change Adapter Settings” option, this will show the current network connections.

Following the process, click on the properties option, under the Local Area Connection options, which comes for wired connections. For a wireless connection, click on the Wireless Network Connection options.

The next option involves displaying the IP version box. On clicking the same, a box will open to change the preferred DNS server and alternate DNS servers as well. For users with IPv4, the Google DNS is 8.8.8.8 and 8.8.4.4 respectively.

In the end, restart the browser to see the change.

For MAC Users

Step 1: Open the System Preference bar, situated on the top left of the screen.

Step 2: In the following step, click on the advanced options to open up the page containing DNS server addresses

Step 3: In the final step, adding the IPv4 DNS address from Cloudflare, 1.1.1.1, and 1.0.0.1 will complete the setup.

6. Check Your Antivirus Installation and Computer Firewall Settings

Another common reason for triggering the ERR_CONNECTION_CLOSED error is your aggressive Antivirus installation or Firewall settings.

In order to protect your system or computer from malware and cyber-attacks, your firewall might be blocking the website you are visiting and as a result, an error message is displayed on your Chrome browser.

To identify the main culprit, you have to temporarily deactivate your antivirus installation or Firewall for a short time and see if the problem got fixed. If it is able to solve the issue, then you have to either reset your computer firewall settings or get another antivirus program.

For now, let us see how you can temporarily deactivate the Firewall on your Windows PC as well as macOS.

For Windows Computers

Go to Windows and the start button located at the extreme left-bottom corner of your screen, and type “Windows Defender Firewall” to search.

Now, click on the Windows Defender Firewall as shown in the picture, and a Windows Defender Firewall window will pop up, where you can find different options.

Select “Turn Windows Defender Firewall on or off“.

For macOS

In macOS devices, you need to Open the Security and Privacy section in your system preference settings.

7. Either Update or Reinstall Your Chrome Browser

Sometimes, the outdated version of Chrome can create issues or trigger errors like ERR_CONNECTION_CLOSED out of misconfiguration or incompatibility. This is one of the reasons why you should keep every system or software updated with the latest version available.

Not only does the latest version bring new functionality and features but also brings a lot of bug fixes and compatibility issues. Therefore, to remove all the possibility of causing any problems, it is highly recommended you keep updating your Chrome browser with the latest version available.

To check updates and apply them, the first thing you need to do is to use this shortcut:

Enter “chrome://settings/help” in the address bar of your Chrome browser and it will start automatically looking for new updates. If there are any, update it and relaunch Chrome to finish the process.

On the other hand, if you want to completely install a new fresh copy of Chrome, it is better to reinstall it from the beginning.

For mobile users, if you are experiencing ERR_CONNECTION_CLOSED on an Android device, you can solve this by simply updating the Chrome app from the Play Store, and in iOS devices updating chrome from the App Store.

8. Disable Installed Chrome Extensions

It is also seen that some Chrome extensions that you have installed might also be responsible for triggering the error ERR_CONNECTION_CLOSED. This can happen due to multiple reasons; some extensions might interfere with the connection somehow or get corrupted.

Whatever the reason is, the best thing you can do is to disable all of the installed Chrome extensions and see if the problem got fixed. If it does, then enable each extension one by one and simultaneously try to access the website again and again. This way you will be able to find out the exact faulty Chrome extension that is causing the issue.

Once you figure out the culprit, delete it, and you are done.

To view and manage all your Chrome extensions, you can use this shortcut method by simply putting the address “chrome://extensions/” in the address bar or go to settings > Extensions.

9. Utilize the Chrome Clean-up Tool

Google Chrome provides you with an inbuilt clean-up tool to debug issues that might be happening in Chrome. The Clean-up tool will scan your whole computer and find any bugs or malware that might encounter Chrome and trigger errors like ERR_CONNECTION_CLOSED to display.

To use this helpful tool, you can use the short by simply putting the address ” chrome://settings/cleanup” in your Chrome browser’s address bar and clicking on the “Find” button to start scanning your computer for harmful software.

10. Restore Settings in Chrome to their Original Defaults

To remove all the possibilities of triggering the error from your Chrome browser, you can restore or reset Chrome settings to their original defaults. Google chrome provides this option in its settings section itself, and to reach there you need to put the following address in the Chrome address bar.

chrome://settings/privacy

On this page, you will see a lot of options listed on the left side of the screen where you have to look for the Reset and Clean Up option and click to open it.

Now you will have Reset settings to their original default and clean up a computer as options. Choose Reset settings to their original default > Restore settings.

Note: While resetting or restoring Chrome settings to their original default, it will remove all your saved passwords, bookmarks as well and browsing history. Therefore, you must take a backup first and then proceed further.

11. Completely Scan Your Computer for Viruses or Malware

The last and final potential that triggers the error ERR_CONNECTION_CLOSED can be harmful malware or viruses present on your computer. Any malware or virus present on your computer can deliberately hinder the connection between the server and the browser, and as a result, trigger error messages.

However, if you have already used Chrome’s inbuilt clean-up tool, that would have already shown issues. But for complete satisfaction, we would recommend you run a complete malware scan using any reputed malware scanning tool.
