The Internet, which is an immense, ever-growing part of our lives, has taken our world over just as you never thought of it. Simply put, the Internet is a collection of data from different devices that people can view in a single location. A browser helps us browse the Internet at our own discretion as the most convenient way to gather access to the Internet. The ARPANET or Advanced Research Projects Agency Network became the first workable prototype of the Internet in the late 1960s. originally financed from the United States Government.

ARPANET used the technique of packet switching in the Defence Department to allow several computers to communicate on a single network and make managing and moving of files and records easier. The World Wide Web was the first public web browser. It was constructed by Tim Berners-Lee.

Today, Google’s Chrome Browser stands out among a number of other browsers available on the market and successfully made its image as if you were thinking of a Web browser, with Chrome zips in mind. Although it is very common in the past, it also has some errors that cause both frustration and deception among users, the most common errors, or even what can be called a bug you face when you surf the Internet. But to get to overcome a problem, you must first know what it is and how is it really caused, so let us ask the most relevant and important question here,


The ERR_CONNECTION_CLOSED Error is not an error specific to the browser of google chrome which in turn means that you do face this error in a lot of other browsers too(Microsoft Edge and Mozilla Firefox to name a few).

This error simply pops up on the screen with the message that “This Site Cannot be reached” and that the connection was suddenly closed while contacting the website in question.

But we need to run a few checks first, to make sure we know exactly where the problem lies. So, assuming that the user Is using the Microsoft Windows Operating system,

First of all, we need to check the bottom right corner of our screen, to check the adapter settings of our computer. There can be 3 responses here. There can either be a cross sign, which means that the network has been interrupted physically in between the router and the user’s PC and the port is not receiving packet impulses as it should, therefore, such an indication is given.

Or, there can be a caution sign (Yellow Inverted Triangle with a black colored exclamation mark) which indicates that the port is functional but there is an error in the packets and that they are not reaching the user properly(indicating that there are no external port errors on the user end of the network). Or, there can be a normal steady-state wherein only the signal strength is shown as a bar graph representation. We conclude that we must ensure that the network is functioning properly by checking for the steady-state of the internet from the lower right corner first.

Next, we must ensure that the same page is reachable on another browser, for this, we must copy the link that we tried to access and paste it into an alternate browser. If the alternate browser is able to access the same website, then we must understand that there is a problem specific to the browser. (i.e. Google Chrome).

Finally, we must check if we are using any proxy server or VPN and if we are, then we must turn it off and try reaching that site again via Google Chrome.

If all of the mentioned checks fail, then we must understand that there is a problem in the browser itself and nothing else.

How to Fix the ERR_CONNECTION_CLOSED Error in Google Chrome
