Command => netsh winsock reset




Step:3 Disabling Proxy Servers and VPNs

Proxy servers and VPNs provide distinct avenues to maintain online anonymity. Each method contributes uniquely to data transmission, and in certain scenarios, they can trigger issues such as the “ERR_CONNECTION_RESET” error. If you are employing either of these intermediary technologies, consider temporarily disabling them for testing purposes. In the case of VPNs, an alternative could be refraining from their use.

To deactivate a proxy server, navigate to the “Internet settings” menu, accessible through the control panel;




Once you have navigated through the Internet options settings “Internet Properties” dialogue box will appear on that navigate to the “Connections” tab. There you will see an option to remove your VPN connection, choose the available VPN and click on “Remove” it. You can check the below image to proceed with the steps mentioned;





To deactivate the settings, you can check the LAN settings on the same page and remember to uncheck the “proxy server” and click “ok” as shown in the below image to deactivate the “proxy server.”




Step:4 Refreshing DNS Cache:

The process of translating domain names into numerical IP addresses is crucial for internet functionality. To prevent repetitive conversion every time a website is visited, DNS servers and browsers store address records in the DNS cache. While this speeds up loading times, it can also result in issues like the “ERR_CONNECTION_CLOSED” error when outdated entries clash with the current website version. A potential way of performing a DNS flush, which entirely purges the address cache.

You can accomplish this by executing the below command in the command line;

Command => ipconfig /flushdns




You can execute the below command to clear the Chrome browser’s DNS cache, it will be placed in the browser’s URL

Command => chrome://net-internals/#dns

You will be navigated to the Chrome DNS page, there you will see a menu called “clear host cache” Click on it to clear chrome’s DNS cache.



Step: 5 Changing the DNS servers:

The potential issues extend beyond the cache of the utilized DNS server. If the server’s availability is restricted or it is entirely offline, it could lead to connection interruptions and trigger the appearance of a Chrome error message.
