To understand the significance of the ERR_CONNECTION_CLOSED error we need to briefly describe what happens behind the scenes in Chrome when you try to browse a website.
Whenever you click on links or type a website’s domain name in the address bar, Chrome must establish a connection with the server hosting the website.
When Chrome connects, it will ask for specific files needed to render the website, such as all code, images, etc.
You may receive an ERR_CONNECTION_CLOSED error message if something goes wrong with your Internet connection or computer, which prevents Chrome from establishing or maintaining a connection.
This error message appears due to Chrome’s failure to connect to the website’s server and render the webpage. To fix the ERR_CONNECTION_CLOSED error you need to find out what is wrong with Chrome that stops the browser from connecting to the website’s server.
What causes the ERR_CONNECTION_CLOSED error?
Some of the common causes of disconnection errors are as follows:
Null root: The host or server may go offline, rendering the system unavailable.
Using all server resources: Current hosting usage has reached server capacity.
A slow or unpredictable Internet connection can disrupt network connectivity.
A damaged cache in the browser or in DNS can affect connectivity.
Virtual Private Network (VPN) service issues: VPN software settings may be set to restrict certain websites.
How to fix the ERR_CONNECTION_CLOSED error
A common Google Chrome error that shows a browser’s attempt to connect to a website has been rejected is the ERR_CONNECTION_CLOSED error.
Usually, this is a client-side problem caused by regional network configuration, browser add-ons, synchronization, or third-party software. Server outages can sometimes bring it on.
Other browsers experience the same problem. “. This website cannot be reached,” according to Microsoft Edge Mozilla Firefox, however, shows the “Unable to connect” notification.
You can solve the problem using one of the simple ways listed below.
Make Confirm, you have an internet connection.
Check if your internet connection is still active when you see the ERR_CONNECTION_CLOSED alert When your internet connection is down, Chrome will display this warning while browsing a webpage.
Unplugging a cable, going out of Wi-Fi range, router issues, a weak data signal on your smartphone, or other situations can cause internet connectivity to drop. Open a desktop or mobile app to determine if the internet is working. If you use Spotify, for example, you can try to play a song that you haven’t downloaded.
The fact that Spotify can still play music indicates that there is a problem with Chrome and that your internet is working properly.
Reset the network settings
Even if your Internet connection is working fine, one or more network setup errors on your device may prevent access to the website and cause an ERR_CONNECTION_CLOSED error to appear.
Usually, the cause of the ERR_CONNECTION_CLOSED error is a TCP/IP setup error that can be fixed by resetting your network settings.
Clear your DNS cache
To avoid translating domain addresses each time a website is browsed, DNS servers and browsers create a record of address entries known as DNS caches. The result is faster loading speed; However, if obsolete or incompatible entries are not compatible with the latest version of the website, they may cause technical problems such as ERR_CONNECTION_CLOSED errors. DNS flushing, which clears the address cache, can help remedy this problem. For example, by using the following command at the command line, you can clear the system cache:
ipconfig /flushdns
Chrome’s DNS cache must first be cleared by typing the following command in the address bar:
chrome://net-internals/#dns
As a result of this action, DNS settings will be visible in the “Net Internals” hidden options menu. You’ll also see the “Clear Host Cache” button, which you’ll need to click to clear the cache with a list of active and expired DNS entries.
Clear Chrome browser history
Your Chrome browser often stores some website files in cache memory to improve user experience and speed up browsing. If something goes wrong and your cache memory gets corrupted, WordPress errors like ERR_CONNECTION_CLOSED will start appearing.
To clear the cache in the Chrome browser, navigate to Chrome browser settings. Then, click the Clear Browsing Data button after selecting Privacy & Security. Select the data you want to delete, then click on the Clear data option.
Disable firewall and anti-virus software if necessary
The use of security software is essential because of the numerous, varied risks that come with your regular activities on the Internet. Modern firewalls, real-time scanners, and similar programs usually work fine, but they are not impenetrable and can cause ERR_CONNECTION_CLOSED errors. Incorrect setup, programming errors, or outdated application files can cause such errors. In this case, see if upgrading them fixes the problem or if the URL of the target website is already blacklisted by one of your security tools.
If that doesn’t work, you can try turning off your firewall and antivirus program briefly before refreshing the website.
Update or reinstall the Chrome browser
Sometimes, issues or errors like ERR_CONNECTION_CLOSED can occur due to misconfiguration or incompatibility when using an older version of Chrome.
This is a reason to use the most recent version of any software or system. The latest version includes numerous bug fixes, compatibility issues, and additional functionality and features.
Therefore, it is strongly recommended that you regularly update the Chrome browser to the latest version to eliminate the risk of any issues arising.
Disable Chrome extensions
Additionally, it has been observed that some Chrome extensions you have installed may also be responsible for the ERR_CONNECTION_CLOSED issue.
Several things can cause this, including some extension corruption or interference with the connection. Whatever the reason, the best step to fix the ERR_CONNECTION_CLOSED error is to close any installed Chrome extensions and check if the issue is resolved.
If this is the case, turn on each extension individually when trying to access the website repeatedly. This way, you will be able to identify the exact problematic Chrome extension that is the root of the problem.
Use the Chrome Cleaning Tool
Chrome includes a cleanup tool to help troubleshoot problems that may occur in this browser. This useful program can check your computer for harmful malware that can block Chrome or cause problems like ERR_CONNECTION_CLOSED.
You can quickly access this tool and start checking your machine for malicious software by entering the URL “chrome:/settings/cleanup” in the address bar of your Chrome browser and selecting “Find”.
Reset Chrome settings
You can restore or reset your Chrome settings to defaults to ensure that there is no more chance of problems while using the browser. This can be done quickly with tools built into Chrome. To do this, follow these steps:
- Access Chrome settings.
- After selecting the Reset and Clean Up option click Restore settings to their defaults.
- Select the Reset Settings button.
Change DNS settings
Users can temporarily change DNS server addresses when facing problems as ISPs usually provide them. There are currently two well-known public domains with a significant user base and a reputation for security The first is Cloudflare, and the second is Google’s Public DNS.
Some DNS servers are not running but may encounter ERR_CONNECTION_CLOSED errors. In this situation, switching to Google and Cloudflare servers will help you fix the ERR_CONNECTION_CLOSED error.
You can set up your computer to use Cloudflare’s free 1.1.1.1 DNS service, which is a reliable and privacy-conscious choice that should solve the problem.
Check your computer for malware and viruses
One of the most likely reasons for the ERR_CONNECTION_CLOSED error is potentially dangerous software or viruses already installed on your computer.
Any malware or viruses on your computer can interfere with the browser’s ability to communicate with the server, resulting in error messages.
However, if you were already using Chrome’s built-in cleanup tool, those problems would have been found.
However, we recommend you use a reliable malware scanning application for a thorough malware scan.
