How to Fix ERR_CONNECTION_CLOSED?

There are, in total 10 popular ways to fix this issue; in most cases, any one of the 10 steps will fix the issue completely. If the problem is fixed then the problem is on the website’s server and not in our system. Now let’s have a closer look at the 10 steps. 

1. Check your Internet Connection

When you get the warning ERR_CONNECTION_CLOSED, you should first verify your internet connection to ensure it’s still active. Chrome will display this warning if your internet connection failed just as you were trying to view a webpage.

A cable coming disconnected, moving out of wifi range, a problem with your router, a poor data connection on your phone, etc., are all possible reasons you lost your internet connection. So try checking your internet connection.

2. Use a VPN (Virtual Private Network)

Your internet service provider (ISP) could be banning that particular website if you only ever see the ERR CONNECTION CLOSED notice while attempting to visit it.

3. Disable Proxy Server

Using a VPN service may fix the error, but in some cases disabling the Proxy Server may help you to fix the issue. If your proxy server isn’t functioning properly, it may also result in the ERR_CONNECTION_CLOSED warning.

In the situation we described above, a VPN can be a solution, but it can also be a problem if it isn’t functioning correctly, it can also be a problem.

Try turning off your proxy servers to see if it solves the issue. If Chrome begins to function normally once again, you have identified the problem. You must close the software or disable it to disable a VPN. 

From Chrome’s Settings > Extensions menu, you can disable any Chrome extensions you use as a VPN.

You might need to access the connection settings on your device to disable a proxy server. On Windows, follow these instructions:

Disable Proxy Server - ERR_CONNECTION_CLOSED Error
  1. Look for “internet options” in the Control Panel after opening it.
  2. To view your network settings in a pop-up, click the “Internet Options” result
  3. In the Internet Properties pop-up, select the “Connections” tab.
  4. Select “LAN settings.”
  5. “Use a proxy server for your LAN” and “Automatically detect settings” should both be unchecked.

4. Clear your Browser Cache

Chrome keeps part of a website’s static files in a local cache known as the browser cache to speed up your browsing experience. This cache may include incorrect data that might result in problems like the message ERR_CONNECTION_CLOSED.

Enter the following address into your Chrome browser’s address bar to delete the cache: “chrome:/settings/privacy” Select “Clear browsing data” after that. Make sure to tick only “Clear Images and Files” and “Clear Data.”

5. Flush DNS Cache

Besides clearing the browser cache, you might also need to clear the DNS cache. When you visit a website, your browser or computer requires a means to find the server’s IP address linked to the domain name you are seeing. Your computer uses the DNS, or domain name system, to find the IP address.

Your computer will save the IP addresses of servers in a local DNS cache to help you browse the internet more quickly. The ERR_CONNECTION_CLOSED message can be sent if the data in this cache is inaccurate for any reason.

You can clear your computer’s DNS cache to resolve any potential issues. A new connection to the legitimate IP will be forced as a result.

6. Change your DNS

You may set up your computer to utilize several DNS providers to conduct this lookup. However, the ERR_CONNECTION_CLOSED notice could appear if there is a problem with the service provider that your computer is set up to utilize.

You may resolve this by setting up your computer to utilize Cloudflare’s free 1.1.1.1 DNS service (or Google DNS), a dependable and privacy-conscious choice that should address the problem.

If there is an issue causing the error, changing the DNS server may help. To do this, follow these steps:
