What does " ERR_CONNECTION_CLOSED "mean?
You you may see the message "ERR_CONNECTION_CLOSED " with any website. Chrome informs you that the data transfer that would have been necessary to establish the connection has been interrupted .

Correct the error "ERR_CONNECTION_CLOSED ": how it works
In addition to the message "ERR_CONNECTION_CLOSED ", first proposals for very different solutions are generally given, which highlights the real problem with the message: it does not reveal any details on the reason for the interruption of the connection . This means that there is no basic solution to correct the error "ERR_CONNECTION_CLOSED ", but only various solutions that you can try one by one. We have compiled for you the most promising methods to solve the problem under Windows.
Solution 1: check the Internet connection and restart the router if necessaryssaire
Before going into your system configuration and from the browser to find the source of the error "ERR_CONNECTION_CLOSED " and correct it, a simple check of the Internet connection is recommended. On Windows, for example, you can do this via the network icon in the notification area (also known as the system tray). You can see not only the network you are currently connected to, but also the connection status.
Use the icon in the Windows notification box to open the Network and Sharing Center and get more detailed information on established connections.
With a good Internet connection, you should find the entry " Internet access " (see screenshot). If not, make sure that all cables from your network device are properly connected. If this is the case, you can also try to restart the router by temporarily cutting the power to the device (30 seconds or more).
If you are connected to the Internet by WLAN and you can switch to a cable connection, use this option as soon as your browser displays the message "ERR_CONNECTION_CLOSED ". Indeed, spontaneous disconnections are not uncommon with a transmiWireless, especially if you usually experience fluctuations in signal strength.
Solution 2: reset settings network
Connection problems that lead to errors such that "ERR_CONNECTION_CLOSED " can also be caused by problems in the TCP / IP configuration of the system. However, you can resolve this issue by resetting the TCP / IP stack settings to their original state . You only need administrator rights and the command line tool Netshell (netsh), which is installed by default since Windows 2000. To launch the command prompt as administrator, first click on the Start menu (Windows icon) and enter the term "cmd " in the search bar. Then right-click on the cmd application presented as a search result and select "Run as administrator:
The "Internet options" button is visible in the display with icons by default - if you have activated the category view, you must first select "Network and Internet.
Then go to the "Connections tab. In the upper window you will find a list of configured VPN connections. If you have installed a VPN connection, you can also get rid of it here using the "Remove :
If you delete a VPN connection, you can re-establish it later via the "Add VPN" button.
The configuration of proxy settings works via the " LAN settings option, which is located in the lower part of the window :
The "LAN Settings button under the category" Local Area Network Settings.
Under "Proxy server, uncheck" Use a proxy server to disable the configured proxy .
If you have extensions installed with proxy or VPN functions, you must also deactivate or remove them.
Solution 4: clear the DNS cache
Resolve s namesDNS ervers is one of the most important Internet mechanisms. So that the conversion of domain addresses to their numeric equivalents does not have to be performed each time a website is accessed, DNS servers and browsers create entries for addresses in the DNS cache. This results in faster loading times, but also technical problems such as the error "ERR_CONNECTION_CLOSED " in the event that the entries are obsolete and are no longer synchronized with the current version of the site. One solution may be the Flush DNS , which completely clears the address cache . For example, you can reset the system cache using the following command from the command line:
ipconfig / flushdns
To clear the cache Chrome DNS , you must first enter the following in the address bar:
chrome: // net-internals / # dns
This opens the DNS settings in the hidden options menu "Net Internals. In addition to a list of valid and expired DNS entries, here you will find the "( Clear host cache ) button which can be used to clear the cache.
In the menu" Net Internals you will not only find the DNS cache of Chrome, but also various statistics (for example on data consumption or HTTP sessions created).
Solution 5: modify the DNS servers manually
Not only can the DNS server cache become a problem, but if the server availability is limited or if the server is completely out of service , then the connection may also be interrupted and the Chrome error message may appear. However, you can manually enter a local name on the server and therefore transfer the name resolution task to another server. To do this, proceed as follows:
Open the overview of active network connections , for example via the Network and Sharing Center or using the [Touche Windows] + [R] followed by the entry "ncpa.cpl.
The ncpa.cpl control panel allows Windows users to directly access the connection display network.
Now right-click on the network connection through which you are connected to the Internet and click " Properties in the context menu (requires administrator rights) Find the entry "Internet Protocol Version 4 (TCP / IPv4) and open the protocol configuration menu with a double click. Leave the IP address settings as they are (address entered automatically or manually) and sselect "Use the following DNS server addresses at the bottom of the menu. Then enter the server addresses of your choice. For example, the addresses of Google servers ( 18.104.22.168 and 22.214.171.124 ) are recommended:
As an alternative to Google DNS addresses, you can enter any other DNS server address like that of the CND provider Cloudflare (126.96.36.199 / 188.8.131.52) in the IP properties ).

Solution 6: check firewall and antivirus software and disable them if necessary
Given the many and various dangers that accompany our daily activities on the Web, using security software is imperative. But while modern firewalls, real-time scanners, and other software are generally very effective, these tools are not foolproof. Incorrect configurations, software errors, or outdated program files can cause connection errors such as "ERR_CONNECTION_CLOSED ". In this case, check whether updating these services can resolve the problem or whether the address of the target site is blacklisted by one of your security programs. Yesyou can't, you can try temporarily disabling the firewall and antivirus software, then reload the page .
Solution 7: Checking malware with Chrome Cleanup
Even the best security configuration cannot offer 100% secure protection against malware (so-called "malware"). Therefore, you can never rule out the possibility that your system could become infected with malware responsible for disconnections. For example, Chrome offers its own malware detection and removal solution , which you can launch directly in your browser settings. To do this, first open the settings menu by clicking on the three dots at the top right of the screen and then selecting " Settings :

Extensions are important building blocks for extending the functionality of software or in particular the Google browser. Thousands of free extensions are available in the Chrome Store. These are extremely handy, but they also cause problems such as the error "ERR_CONNECTION_CLOSED " (especially if the extensions are no longer compatible with the browser update strong To verify if an installed extension is the cause of the error message, temporarily disable it . Just enter the URL chrome: // extensions in the bar address and move the sliders of each extension to the left:
Disabled extensions can be reactivated at any time by moving the cursor to the right again.
